Don’t miss it.</p><h3>1. <strong>Swap downtime for runtime</strong></h3><p>High-throughput testing laboratories as well as QA/QC labs need to deliver quality results on time.&nbsp; In a situation where a laboratory needs to quickly solve a contamination issue, for example, or needs to quickly recover a correct instrument behavior, the module replacement allows you to <a target="_blank" rel="noopener noreferrer" href="https://assets.thermofisher.com/TFS-Assets/CMD/brochures/sp-74147-gc-modularity-TRACE1600-sp74147-en.pdf"><strong>restore running conditions in less than 30 minutes</strong></a>, including cooling and powering down the instrument, disconnecting the column from the original injector module, removing the module, and plugging in the new one, re-connecting the column, and powering up the GC again. The same operation on a conventional GC design would require a service call and a day of instrument downtime.<br>In a situation where the laboratory has a spare module available, no troubleshooting actions are needed and no service call, reducing instrument downtime to half an hour —all with the limited investment of a spare module.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Scientific_4_Ways_to_Increase_Your_GC_Lab_s_Efficiency_2_ec40ea6c18.jpg" alt="Thermo Scientific: 4 Ways to Increase Your GC Lab’s Efficiency" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Scientific_4_Ways_to_Increase_Your_GC_Lab_s_Efficiency_2_ec40ea6c18.jpg 234w," sizes="100vw" width="719" height="479"></p><h3>2. <strong>Optimize running costs</strong></h3><p>A way to increase your laboratory’s efficiency is to make better use of the available resources and optimize running costs by reducing underutilized instrumentation in the lab. The modular concept of unlimited GC configurations and the ability to share modules on any Thermo Scientific TRACE 1300 and 1600 Series GC, multiplies the analytical possibilities. With the increased flexibility gained from modular capabilities, an instrument no longer needs to remain idle because it’s not configured to run particular sample types. More efficient use of your GC instruments optimizes costs and accelerates the return on investment.&nbsp;&nbsp;</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Scientific_4_Ways_to_Increase_Your_GC_Lab_s_Efficiency_3_9934c72df9.jpg" alt="Thermo Scientific: 4 Ways to Increase Your GC Lab’s Efficiency." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Scientific_4_Ways_to_Increase_Your_GC_Lab_s_Efficiency_3_9934c72df9.jpg 156w," sizes="100vw" width="617" height="617"></p><h3>3. <strong>Maximize your investment</strong></h3><p>Start-up, non-routine laboratories may initially face limited budgets, so investments need to be prioritized. Short-terms requirements are clear but future requirements remain uncertain; the same GC may be required for different applications. So which configuration should be considered to balance the initial investment with growing analytical requirements?</p><p>With conventional GC, saving money today may mean higher costs in the future.&nbsp; Through modularity, you can invest based on current requirements and benefit from additional modules when they are necessary, with no additional fees. &nbsp;Modularity opens up to high flexibility to quickly adapt the GC system to current and future needs and easily address evolving priorities.</p><h3>4. <strong>Free up bench space</strong></h3><p>With a width of only 44 cm (17.3 inch), the compact size of the TRACE 1600 series GC allows your lab to optimize valuable bench space, allowing you to position more instruments in a limited space. Additionally, having the capability to quickly install and uninstall injectors and detectors and having spare iConnect modules on hand for fast replacement, eliminates the need for maintaining a duplicate GC back-up instrument, removing associated cost of operation and further optimizing valuable bench space.</p><p><strong>The modular design of your next GC system will revolutionize the way you work in your laboratory.</strong></p><blockquote><section><p><strong>Dr. Daniela Cavagnino</strong></p><p>Dr. Daniela Cavagnino is global Product Marketing Manager for GC and Autosampler/front-end solutions at Thermo Fisher Scientific.

Agilent Technologies: Py-GC/MS/MS Microplastic Analysis of Samples Containing Interfering Substances</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_microplastic_analysis_pygcmsms_5994_7637en_agilent_1_6caa53726f.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Microplastics, defined as plastic fragments with a particle size of 5 mm or less, originate from various products, such as cosmetics, clothing, food packaging, and plastic waste. Microplastics have been detected in water, soil, and air environments,5 as well as in food and within living organisms.7 Consequently, numerous analytical techniques are being developed to investigate the extent of microplastic contamination and its impacts.&nbsp;</p><p>Microplastics can be seen with the naked eye or a microscope when the particle size is large, but observation is difficult when the size is small, and quantitative analysis by type of plastic is difficult. Techniques using spectroscopic instruments, such as IR or Raman, or thermal analysis instruments such as Py-GC/MS or thermal extraction desorption (TED)-GC/MS have been widely used.1, 2, 3, 4 IR and Raman spectroscopy can be used to identify the type, shape, size, and count of microplastics on filters after sample preparation and filtration. These techniques rely on spectroscopic analysis of the microplastics retained on the filter. For Py-GC/MS or TED-GC/MS, the microplastics collected on the filter are thermally decomposed, and the resulting compounds are analyzed with GC/MS, allowing for the quantification of each type of microplastic8 (by weight). In particular, Py-GC/MS has recently been recognized as an ASTM International method11 and is widely applied as an analytical method for analyzing microplastics in drinking water.12 In the case of environmental samples or food samples with complex matrices, additional matrix effects can negatively impact analytical performance or result in thermal decomposition products that cannot be separated from microplastic thermal decomposition product peaks, causing interference and overlapping with target ions.6&nbsp;</p><p>In this application, we applied Py-GC/MS/MS (MRM mode) to microplastic analysis to determine whether accurate quantitative analysis of microplastics is possible even in samples containing complex matrices.</p><h5><strong>Instrument and analysis conditions&nbsp;</strong></h5><p>The instruments used were a Frontier Lab pyrolyzer (<a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=42&amp;search=Py-3030D"><strong>Py-3030D</strong></a>) and an Agilent <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=8890+GC"><strong>8890 GC</strong></a> coupled to a <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=7000E+triple+quadrupole+gc%2Fms"><strong>7000E triple quadrupole GC/MS system</strong></a>. The temperature of the pyrolyzer was set to 600 °C, as shown in Table 1, and the components produced by thermal decomposition were passed through the GC inlet (320 °C, split 50:1), cryo-focused by liquid nitrogen applied to the front end of deactivated metal capillary column (UA-5, 30 m x 0.25 mm x 0.25 µm) in the Microjet Cryo Trap, separated by the GC oven temperature program after about 3 minutes, and transferred to the mass spectrometer. The analysis conditions are shown in Tables 1, 2, 3, and 4.</p><h4><strong>Results and discussion</strong></h4><h5><strong>Chromatogram</strong></h5><p>Chromatograms resulting from the analysis of the microplastics calibration standard (MPCS) that includes 11 types of microplastics are shown in Figure 1 for both Scan and MRM modes. The Scan mode total ion chromatogram (TIC) can be processed into extracted ion chromatograms (EIC) to confirm the target ion (m/z) for each indicator peak, as seen on the left side of Figure 1. The MRM TIC and EIC are shown on the right side of Figure 1. As can be seen, MRM mode can reduce matrix interference and enhance selectivity. Calibration curves can be created using either Scan or MRM mode using concentration of the MPCS.</p><h4><strong>Conclusion</strong></h4><p>We have established a quantitative analysis method using Py-GC/MS/MS (MRM mode) for complex matrix samples and trace levels of microplastics.&nbsp;</p><p>Under the established Py-GC/MS/MS (MRM mode) conditions, the linearity of the calibration curves generated for the 11 types of microplastics, ranging from several hundred ng to several µg, was excellent (R² &gt; 0.99). Compared to Scan (Target EIC) mode, noise is reduced by two to several times when analyzed in MRM mode, and accordingly, the S/N ratio is increased when analyzed in MRM mode, enabling the detection of microplastics with better selectivity. In addition, when there is matrix interference during sample analysis, more accurate quantitative results can be obtained by applying the MRM mode, and Py-GC/MS/MS (MRM mode) can be very useful for quantifying complex matrix samples and trace levels of microplastics.</p><h3><strong>2. MDCW: Analysis of (micro-)plastic-associated chemicals released into marine environments by comprehensive multidimensional gas chromatography-mass spectrometry</strong></h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/MDC_2025_Poster_d31ebb1c76.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Plastic materials contain many different chemicals, which include functional additives as well as trace levels of non-intentionally added substances. Plastic released into the environment acts as a vector for these chemicals, which may cause harm to exposed organisms. The complex mixture of chemical classes and concentrations within plastics is a challenge for analysis, which can be addressed through the use of multidimensional analytical approaches.&nbsp;</p><p>Here, the chemical composition of different polymer samples was analysed using comprehensive multidimensional gas chromatography coupled to time-of-flight mass spectrometry. Ultrasonication assisted extractions with solvent represents a ‘worse-case-scenario’ in relation to environmental leaching, and provides a starting point for non-target analysis of microplastic leaching in marine environments.</p><h4><strong>Results</strong></h4><p>All the virgin polymer samples released chemicals under organic extraction. As shown in Figure 1, the Hexane DCM:MeOH MeOH EtOAc number of compounds released by each polymer was influenced by the solvent used for the extraction. Additionally, the conventional polymers released a higher number of chemicals than the biopolymers, particularly LDPE and PP.&nbsp;</p><p>The high number of compounds released by LDPE and PP is due to the release of polymer-derived alkanes. The use of GC ×GC enabled separation and identification of other plastic-associated compounds from the alkane series (see respective chromatograms). In contrast, the other polymers released a range of compound classes. Some of the compounds identified in the extracts, for example phthalates, are detrimental to both human and environmental health.&nbsp;</p><h4><strong>Conclusion</strong></h4><p>Chemical extracts from several polymer samples demonstrated that virgin polymer samples contain chemicals which are not chemically bonded to the bulk polymer material – and therefore have potential to be released into the environment. Future leaching studies can be informed by the chemical identifications made, and increase the confidence that those compounds identified in leachates did originate from the respective polymer.</p><h3><strong>3.

They are known as volatile organic compounds that contribute to aroma. However, recent studies in various countries have reported health concerns regarding these compounds and monitoring of furan and alkylfuran has been recommended in the EU1) .&nbsp;</p><p>These compounds are frequently measured using the HSGC/MS method, which is convenient and effective when present at relatively high concentrations. However, for samples containing low concentrations, pretreatment for concentration is necessary. This Application News article describes a method using an SPME Arrow and GC-MS/MS system that enables more consistent analysis even at trace concentrations in complex matrix samples.</p><h4><strong>Instrument Configuration and Analytical Conditions</strong></h4><p>The analysis was performed using an AOC-6000 Plus multifunctional autosampler and a <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=GCMS-TQ8040+NX"><strong>GCMS-TQ8040 NX </strong></a>triple quadrupole gas chromatograph mass spectrometer system (Fig. 1). The AOC-6000 Plus is a multifunctional autosampler that can automatically switch between various sample injection methods, such as liquid injection, headspace injection, and solid-phase microextraction (SPME), depending on the sample and purpose (Fig. 2). In this analysis, an SPME Arrow, which offers improved durability compared to a traditional SPME fiber, was used forsample analysis. When using sampling methods involving concentration, such as the SPME method, matrix-derived impurities may also be concentrated, making it difficult to improve sensitivity due to interference from impurities. In this analysis, high sensitivity for analyzing furan in processed foods was achieved by using the SPME method in combination with the MRM mode of the triple quadrupole GC-MS system.</p><h4><strong>Comparison of SIM and MRM</strong></h4><p>To confirm the improvement in selectivity with MRM, analysis using the SIM mode was also conducted. Generally, the MRM mode of a triple quadrupole GC-MS system offers better selectivity compared to the SIM mode, leading to higher sensitivity and more consistent detection. Fig. 5 shows the SIM and MRM chromatograms of four components detected in baby food. While each component was detectable with both modes, the MRM mode provided higher selectivity, whereas the SIM mode was more susceptible to interference from impurities. Therefore, manual peak integration or changes to the quantitative ions may be required in the SIM mode depending on the sample.</p><h4><strong>Conclusion</strong></h4><p>Quantitative analysis of furan and alkylfuran in processed food was conducted using an SPME Arrow and a triple quadrupole GC-MS system. The AOC-6000 Plus multifunctional autosampler allows for highly sensitive and reproducible quantification of furan compounds using the SPME Arrow method. Additionally, by enhancing selectivity with the MRM mode of the triple quadrupole GC-MS system, more reliable analytical results were obtained.</p><h3><strong>4.

Agilent Technologies / ASMS: Optimizing Hydrogen Carrier Gas on GC/MS Using the HydroInert EI Source and 5Q Columns&nbsp;</strong></h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/ps_gc_gc_5q_columns_ei_source_asms_2025_mp_358_en_agilent_c5cf1876f0.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Hydrogen is widely recognized for its benefits in gas chromatography (GC), including cost-effective generation in the lab, rapid chromatography, and higher sample throughput. However, its reactivity can lead to hydrogenation and dechlorination reactions in the mass spectrometer electron ionization (EI) source, complicating its application in many scenarios. To address these issues, Agilent has developed a specially designed extractor source for the Inert Plus GC/MSD and triple quadrupole GC/MS systems, enhancing performance with hydrogen carrier gas. The Agilent HydroInert source maintains mass spectral fidelity and allows users to utilize existing helium-based mass spectral libraries.</p><p>This study investigates how the 5Q series of columns impact the performance and durability of the HydroInert source tune. The study involved cycling through 10,000 oven temperature ramps without any injections to assess the effects of column bleed from the 5Q phase. Furthermore, the study examined how the combination of sample matrix and column bleed from the 5Q phase affects source longevity.</p><h4><strong>Experimental</strong></h4><h5><strong>HydroInert Functionality with 5Q Columns (no Injection)&nbsp;</strong></h5><p>An experiment was designed to investigate the effects of ultra low bleed columns (<a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?instrumentationItems=19&amp;manufacturerItems=1&amp;search=HP-5Q"><strong>HP-5Q</strong></a>) on the functionality of the HydroInert source over time. A method simulating a large oven temperature ramp cycle (Table 1) over 12 minutes was created. The syringe was removed from the ALS tower to simulate injections, but to isolate the source of siloxanes to column bleed from the HP-5Q only. 10,000 injections were executed, and a system tune was performed every 100 injection to monitor source parameter shifts.</p><p>The Agilent <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?manufacturerItems=1&amp;search=7000E"><strong>7000E</strong></a> was run in SCAN mode, scanning from 50-450 m/z during each run. Air leaks were detected and immediately remedied when found to ensure the experiment was free from oxides. Liner and septum were not changed during this experiment.</p><h4><strong>Results and Discussion</strong></h4><h5><strong>HydroInert Functionality with 5Q Columns (no Injection)&nbsp;</strong></h5><p>Results of the effects of 10,000 oven temperature cycles on the HydroInert source tune parameters are shown in Figure 2. Repeller and ion body voltages are set automatically by the tune algorithm to maximize the transference of ion on the 7000E. Throughout the 10,000 injections the ion body voltage remained stable. The EM voltage gain across 10,000 injections was as expected. The source was in use for 120,000 minutes during this study and data was being collected throughout the duration of the study in SCAN mode. During this study, three leaks were detected at the MS transfer line and were corrected as soon as they were detected. The leaks are reflected in the spike in O2 percentage. A new ion body will typically have a voltage of 16-22 V on a HydroInert source. When an ion body begins to lose functionality the ion body voltage will begin to rise to compensate for the loss. Eventually the ion body voltage tops out at 29-30 V and the tune begins to show lower abundance of tune ions, until the source fails to tune. In the current study the ion body voltage was set by the tune algorithm between 19-24 V. This is a stable and normal operating range for the ion body. It is important to remember that a single elevated ion body tune is not cause for concern, there needs to be a trend of elevation over time. The overall purpose of this first study was to examine what baseline changes would occur to the HydroInert tune parameters when using a 5Q column in leak free conditions. Water and oxygen are known to speed the liberation of column bleed, which in turn reduces the functionality of the HydroInert source. This study shows that under leak free conditions, with a 5Q column, the HydroInert source can function optimally for an extended period. This study adds to a growing body of evidence that has demonstrated one of the main factors in HydroInert longevity is leak state of the system.</p><h4><strong>Conclusions</strong></h4><p>Agilent HydroInert source longevity is dependent on application and method conditions. However, by using the best practices highlighted above, the longevity of HydroInert parts can be prolonged. The HydroInert source cannot be mechanically or chemically cleaned, thus when source parts show reduced functionality, replacement of the recommended parts is required to restore functionality. Replacement intervals will be method and application dependent.</p><h3><strong>2. Liège University / MDCW: MOSH&amp;MOAH in food ingredients and additives and the advantages of using LC/GC×GC(-FID/TOFMS) for their analysis&nbsp;</strong></h3><ul><li>Presentation</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/FL_02_2025_MDCW_AG_MOSH_MOAH_additives_a05df36b39.pdf"><strong>Full PDF for download</strong></a></li></ul><p>This presentation by Aleksandra Gorska and colleagues (Gembloux Agro-Bio Tech) addresses the analysis of MOSH (mineral oil saturated hydrocarbons) and MOAH (mineral oil aromatic hydrocarbons) in food ingredients and additives, particularly those derived from oils and fats. These contaminants are widespread in the food chain due to packaging, lubricants, or storage conditions. While MOSH can accumulate in human tissues, MOAH—especially those with three or more aromatic rings—pose genotoxic risks. The European Food Safety Authority (EFSA) has recently emphasized a lack of data on such impurities in food additives.</p><p>To fill this gap, the researchers developed and applied an advanced analytical workflow based on <strong>HPLC-GC×GC-FID/TOFMS</strong>, replacing the traditional HPLC-GC-FID approach. This multidimensional technique combines high-resolution separation with both flame ionization detection (FID) and time-of-flight mass spectrometry (TOFMS), allowing detailed structural characterization, efficient removal of interfering compounds, and the ability to separate MOAH by the number of aromatic rings.</p><p>Key benefits of the HPLC-GC×GC-FID/TOFMS system include clearer chromatograms with structured elution patterns, improved purification and separation of complex MOAH profiles, and identification of contamination markers such as DIPN (indicating migration from recycled packaging). Additionally, the system enables <strong>simultaneous quantification of MOAH and polycyclic aromatic hydrocarbons (PAHs)</strong>, which have distinct analytical requirements and toxicological profiles.</p><p>The study concludes that, despite its complexity, the HPLC-GC×GC-FID/TOFMS technique provides substantial analytical advantages and aligns with EFSA’s recommendations. It offers a powerful tool for ensuring food safety in products containing oil- or fat-derived additives, enabling more accurate risk assessments and source tracking of contamination.</p><h3><strong>3. Shimadzu / ASMS: Highly sensitive and efficient analysis of aroma components using trapped Headspace GC-MS&nbsp;</strong></h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/ASMS_2025_MP_352_97902375e7.pdf"><strong>Full PDF for download</strong></a></li></ul><p>The aroma composition of foods has been the subject of considerable research in recent years. It is well known that the presence of volatile compounds and their composition determine the specific aroma of foods and the flavor of the resulting products. Static headspace technique enables high sensitivity analysis of volatile compounds, normally extracting 1 mL of headspace. But in situations where it is necessary to evaluate the total chemical profile, it is known that components in small quantities also affect the overall aroma. Thus, the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?manufacturerItems=3&amp;search=HS-20+NX"><strong>HS-20 NX</strong></a> was used running in "Trap mode", where by using trapped headspace sampling, it is possible to extract much more volume and analyze, not only the majority components, but all the compounds with high sensitivity.&nbsp;</p><p>The system used to achieve the highest sensitivity is the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?manufacturerItems=3&amp;search=HS-20+NX"><strong>HS-20 NX</strong></a> coupled to the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?manufacturerItems=3&amp;search=GCMS-QP2020+NX"><strong>GCMS-QP2020 NX</strong></a> single quadrupole mass spectrometer.</p><h4><strong>Results and Discussion</strong></h4><p>After the incubation time, the acquisitions were done by loop mode and trap mode with 3- and 5-times sample concentration. In this way, it is possible to analyze, via trap, the presence of compounds at trace levels, which cannot be observed when analyzed in loop mode. 18 compounds could be identified in the sample when analyzed in loop mode, whereas in trap mode, 35 were identified.</p><p>Some components such as benzene acetaldehyde, gammacaprolactone, methyl butyrate, o-guaiacol, that have a decisive influence on the overall aroma and flavor were detected only in the trap mode, due to their low concentrations in the sample. Even concentrating the sample 5-times in the trap, it was possible to detect these compounds that require greater sensitivity along with compounds present in high concentrations in the sample, such as butanoic acid, acetic acid, and others, without losing analysis efficiency.</p><h4><strong>Conclusion</strong></h4><p>The improvement in analysis sensitivity when using trap mode can be observed when comparing the area for some components with a major impact on the overall aroma but present in small quantities. When concentrating the sample 3-times in the trap, the peak intensities increased from 351.17 to 1401.08%. And it was still possible to have a significant increase of another 168%, on average, by concentrating the sample 5-times. The peak intensities increased from 521.48 to 2517.86% compared to loop mode analysis.&nbsp;<br>These analyses demonstrate that trapped headspace can be used to determine an overall aroma profile in a single analysis and with a single trapping material. The trapped headspace sampler enables ultra sensitivity analysis, identifying compounds at low concentrations which were undetectable with conventional headspace samplers.</p><h3><strong>4. Thermo Fisher Scientific: Data-driven GC and GC-MS instrument monitoring with SmartStatus intelligent software</strong></h3><ul><li>Technical note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/tn_001883_gc_ms_gc_ms_ms_smartstatus_tn001883_na_en_99ce72eef2/tn-001883-gc-ms-gc-ms-ms-smartstatus-tn001883-na-en.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Rising costs can significantly impact an analytical laboratory’s profit margin, and it is crucial to maintain productivity and ensure maximum asset utilization to stay competitive. To balance increased overhead costs, including analytical gases and staff pay, laboratories must ensure that analytical instrumentation consistently produces results, without interruption. Re-analyzing entire runs due to drops in sensitivity, unnecessary downtime, and underutilization of consumables is expensive and time consuming.&nbsp;</p><p>Thermo Scientific™ SmartStatus™ instrument tracking can help laboratories realize additional cost savings. This is done by using data-driven insights to accurately determine when to perform maintenance and replace consumables and parts, so that the system consistently runs smoothly for all samples and meets specifications in the initial analysis. This ensures that consumables and parts are replaced on the correct schedule and avoids excess instrument downtime.&nbsp;</p><p>SmartStatus instrument tracking is an intelligent instrument health software that allows users to track key aspects of their GC-MS system. It is available as standard on the Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/483"><strong>TRACE™ 1600 GC series,</strong></a> Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/487"><strong>AI/AS 1610 liquid autosampler</strong></a>, Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/484"><strong>ISQ™ 7610 GC-MS series</strong></a>, and the Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/485"><strong>TSQ™ 9610 GC-MS/MS series</strong></a>. In this technical note, the new SmartStatus instrument tracking capabilities are highlighted with examples of how it can enable analytical laboratories to keep instruments producing consistent results.</p><h4><strong>SmartStatus software overview&nbsp;</strong></h4><p>SmartStatus intelligent software, available within Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/76"><strong>Chromeleon™ Chromatography Data System (CDS)</strong></a>, allows monitoring of the entire analytical system including Thermo Scientific™ autosamplers, GC, GC detectors (FID and TCD), and mass spectrometers (MS). Hundreds of key instrument parameters are monitored by SmartStatus software, which provides real-time data and insights informing the user to potential problems before they arise to ensure maximum instrument uptime. This allows users to make informed decisions on which parts of the analytical system require attention and when. By performing preventative maintenance using data-driven guidance, optimal instrument performance is sustained day in and day out. Figure 1 shows the SmartStatus software overview page for a TSQ 9610 triple quadrupole MS coupled to a TRACE 1610 GC and AI/AS 1610 liquid autosampler. This overview page allows a user to quickly determine if the system is ready to run or requires attention.&nbsp;</p><p>For more information on instrument status, there is a detailed view for each part of the system. This next level view shows how many injections have been performed for the various GC consumables, the lifetime of the MS detector and filament, and when the last tune was performed. Figure 2 shows an example of the GC and MS parameters and how they are monitored. Each parameter is represented as a counter gauge. As the usage increases, the gauge changes color to quickly notify the user of any maintenance that is required or will be needed soon. This allows users to plan maintenance in advance to fit it around their schedule and workload. SmartStatus instrument tracking can be monitored directly in Chromeleon CDS, and consumables usage can also be monitored directly on the TRACE 1610 GC touch screen through the dedicated instrument health icon, as shown in Figure 3.</p><p>The ISQ 7610 GC-MS and the TSQ 9610 GC-MS/MS detector lifetime is monitored using a predictive algorithm. This assesses the voltages on the detector and predicts the lifetime remaining on the system so that preventative maintenance can be planned. As the ISQ 7610 GC-MS and TSQ 9610 GC-MS/MS are equipped with the XLXR™ electron multiplier detector as standard, the lifetime of the detector is several years.1 By monitoring the detector intelligently, users can avoid unnecessary downtime. Figure 4 shows monitoring of the detector within SmartStatus software.</p>

New European Wine Scandal on PFAS in Wine

<p><strong>Gas Chromatography (GC) remains a cornerstone in analytical chemistry, particularly for impurity profiling, solvent quantification, and process monitoring. But as industries face increasing complexity—whether it’s trace-level detection in pharmaceuticals or quality control in fuels—the need for more selective, sensitive, and flexible detectors has never been greater.</strong></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Shedding_Light_on_Trace_Level_Impurity_Detection_in_Modern_GC_Workflows_3cde3edd45.jpg" alt="Thermo Fisher Scientific: Shedding Light on Trace-Level Impurity Detection in Modern GC Workflows." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Shedding_Light_on_Trace_Level_Impurity_Detection_in_Modern_GC_Workflows_3cde3edd45.jpg 245w," sizes="100vw" width="1200" height="600"></p><p>GC-LUMA embeds a next-generation vacuum ultraviolet (VUV) detector that bridges the gap between the universal simplicity of an FID, the selectivity of a mass spectrometer, and the robustness required for high-throughput laboratories. This article unpacks the core insights from a recent expert webinar that explored the technology, real-world applications, and data workflows behind the GC-LUMA system.</p><h3><strong>What makes GC-LUMA unique?</strong></h3><p>The GC-LUMA detector operates in the vacuum ultraviolet (VUV) region of the electromagnetic spectrum, where virtually all organic compounds absorb light. This gives LUMA its defining feature: universal detection, with high absorption sensitivity and the ability to differentiate compounds based on their spectral fingerprints.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Shedding_Light_on_Trace_Level_Impurity_Detection_in_Modern_GC_Workflows_2_3ce03ce7c3.jpg" alt="Thermo Fisher Scientific: Shedding Light on Trace-Level Impurity Detection in Modern GC Workflows: Thermo Scientific TRACE 1610 GC equipped with LUMA detector (VUV Analytics Inc.)." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Shedding_Light_on_Trace_Level_Impurity_Detection_in_Modern_GC_Workflows_2_3ce03ce7c3.jpg 242w," sizes="100vw" width="1200" height="773"></p><article><div><p>Unlike traditional VUV detectors that rely on CCD sensors, LUMA uses a 12-channel photodiode array. Each channel corresponds to a specific wavelength band (from ~118 to 240 nm), offering low-ppb sensitivity. It supports stable, linear quantification via Beer’s Law and provides spectral selectivity that enables analysts to distinguish between structurally similar compounds, such as isomers. Another practical advantage is that the LUMA detector does not require a vacuum pump, simplifying the system’s footprint and maintenance requirements. As a result, GC-LUMA allows users to extract both quantitative and qualitative information in a single run, making it a powerful and versatile tool.</p><h3><strong>GC-LUMA in practice: pharmaceutical applications</strong></h3><p><a target="_blank" rel="noopener noreferrer" href="https://catsci.com/people/dr-sam-whitmarsh/">Dr.&nbsp;Sam Whitmarsh of CatSci Ltd</a>.&nbsp;presented several practical case studies from pharmaceutical process development, where GC-LUMA proved especially valuable. In early-stage synthesis projects, such as those involving valsartan routes, GC-LUMA was used for detailed impurity profiling. The detector’s capability to combine impurity, solvent, and water analysis into a single method proved especially useful, particularly when working with compounds that are not easily detected by FID, such as hydroxylamine or water.</p><p>One compelling use case involved the deconvolution of co-eluting solvents. In scenarios mimicking worst-case chromatographic conditions, LUMA successfully resolved overlapping peaks by identifying differences in their absorbance at specific VUV wavelengths. This ability significantly reduces the need for extensive method re-optimization and enables faster turnaround in process development.</p><p><i>“LUMA gives us the selectivity of a GC-MS, but with the ease-of-use of an FID. In some cases, it’s even an order of magnitude more sensitive than FID for low-carbon or polar compounds.”</i> – <i>S. Whitmarsh</i></p><h3><strong>Water by GC: a new frontier</strong></h3><p>Traditionally, water analysis by GC presents challenges. FID cannot detect water, and manual methods like Karl Fischer titration are time-consuming and prone to variability. GC-LUMA changes this dynamic by enabling water detection as part of the routine chromatographic workflow. The detector quantifies water across a wide concentration range, from parts per million (ppm) to percent levels, and demonstrates broad linearity, for example, from 20 ppm to 2%.</p><p>Using internal standards such as tetrahydrofuran (THF), GC-LUMA enhances reproducibility while allowing simultaneous analysis of water, solvents, and impurities. This capability is particularly relevant in oligonucleotide manufacturing and other pharmaceutical contexts where precise control of residual moisture and solvent levels is critical.</p><h3><strong>Smarter data with Chromeleon CDS</strong></h3><p>As explained by <a target="_blank" rel="noopener noreferrer" href="https://theorg.com/org/vuv-analytics/org-chart/rafael-acosta">Rafael Acosta, Product Manager at VUV Analytics Inc</a>., the integration of GC-LUMA with <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/76"><strong>Thermo Scientific Chromeleon CDS</strong></a> provides a seamless data environment that enhances usability and reproducibility. With native driver integration for TRACE 1610 GC and CDS, analysts benefit from a streamlined three-step setup process that includes wavelength range selection, acquisition frequency, and channel configuration.</p><p>Chromeleon CDS further extends the power of LUMA through automatic peak purity scoring and spectral match evaluation. Users can create and manage compound libraries from reference standards and visually confirm co-elutions or potential interferences by overlaying spectral data. In one example, positional xylene isomers, which typically co-elute chromatographically, were clearly differentiated using their VUV absorbance spectra. This integration not only improves confidence in qualitative identification but also aligns with the data integrity needs of regulated environments.</p><p><i>“Chromeleon’s intuitive approach to data analysis provides a way to visualize LUMA spectra data, obtain library matching capabilities and peak purity information, which makes your method development more robust and less questionable in terms of potential coelutions.” – R. Acosta</i></p><h3><strong>All-in-one methods: a new QC paradigm</strong></h3><p>Perhaps the most compelling outcome of GC-LUMA’s flexibility is its potential to consolidate multiple quality control tests into a single analytical method. A case study involving paracetamol illustrated how GC-LUMA could be used for identity confirmation via spectral fingerprinting, assay and impurity quantification, Class 2 residual solvent detection (such as methanol and pyridine), and water determination—all within one injection.</p><p>For QA/QC laboratories, this represents a paradigm shift. By reducing the number of instruments and analytical methods required, labs can achieve greater efficiency, consistency, and throughput. It also simplifies training, documentation, and regulatory compliance.</p><p><i>“When you start to think about application in a manufacturing environment, this could be really advantageous that you’re really coalescing quite a large number of tests into one run. And that could be very effective in terms of cost and speed to release some materials and the number of pieces of equipment that you’d need to have up and running to do that” – S. Whitmarsh</i></p><h3><strong>Filling the analytical gaps</strong></h3><p>GC-LUMA doesn’t aim to replace FID or MS. Rather, it complements them by occupying a unique space in the GC detector landscape. It offers the universality of a TCD, the selectivity of an MS, and the ease of use of an FID—but with enhanced sensitivity and spectral capability. Ideal for routine labs, process development teams, and regulated QC environments, GC-LUMA delivers more than just data: it delivers clarity, confidence, and actionable insight.</p><p>With its spectral power, method simplicity, and seamless data integration, GC-LUMA provides a compelling new option for analysts seeking to elevate their GC workflows and make better-informed decisions based on richer, more reliable information.</p><blockquote><p><strong>Want to learn more?</strong> Watch the full webinar available on-demand <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/webinar/5325"><strong>Shedding Light on GC‑LUMA: Revolutionizing Trace Level Impurities Detection</strong></a>, or explore technical resources at <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/chromatography/gas-chromatography-gc/gc-systems/related-products/vuv-detector.html">VUV Detector for TRACE 1600 Series GC</a></p><p><strong>Visit us on&nbsp;</strong><a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/showcase/72003132/admin/dashboard/"><strong>LinkedIn:</strong></a><strong>&nbsp;</strong>#TRACE1610 #ImpurityAnalysis #GCInnovation #PharmaQAQC</p></blockquote></div></article><section><blockquote><h4><strong>Dr. Daniela Cavagnino</strong></h4><p>Dr. Daniela Cavagnino is Product Marketing Manager for GC and Sampling Solutions.

Unfortunately, these market conditions, increase the likelihood of adulteration in vanilla extracts by use of aroma chemicals that are not naturally occurring. Common adulterants are coumarin (C), ethyl vanillin (EV), eugenol (E), and guaiacol (G).2,3 Adulteration impacts the standard of identity for vanilla extracts established by the U.S. FDA; therefore, flavor companies rely on QC labs to implement reliable and sensitive analysis techniques for screening incoming raw ingredients against expected purity standards before the ingredient can enter a flavor formula on the manufacturing floor. Screening is typically executed with gas chromatography (GC)- based methods adapted from those used in a R&amp;D lab. However, differences in column length, diameter, and phase can make it seem challenging to harmonize GC methods across the R&amp;D and QC functions within a company due to the different analysis objectives of the respective laboratories.&nbsp;</p><h4><strong>Experimental Goals</strong></h4><ul><li>Demonstrate the ease of the Agilent Method Translator in harmonizing GC methods for multiple columns and gases&nbsp;</li><li>Establish method precision, linearity, and resolution on standards of vanilla-like adulterants using the translated methods&nbsp;</li><li>Successfully showcase the method translation using store-bought extracts to verify the integrity of the fastest GC method on samples containing matrix&nbsp;</li><li>Screen for and quantify any vanilla adulterants in the samples of vanilla extracts with the goal of detecting no adulterants using the fastest GC method.</li></ul><h4><strong>Experimental&nbsp;</strong></h4><ul><li><strong>GC System:</strong> <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=8850+GC"><strong>Agilent 8850 GC</strong></a> with <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=7693A+Automatic+Liquid+Sampler"><strong>7693A Automatic Liquid Sampler</strong></a></li></ul><h4><strong>Conclusions</strong></h4><h5><strong>Method Translation</strong></h5><ul><li>The method translator tool provided an easy conversion of a 50-minute-long method to one that is &lt; 5 minutes resulting in a speed gain of 10-fold and 14-fold, for He and H2 carrier gases, respectively (Figures 2 and 3)&nbsp;</li><li>Resolution of analytes were &gt;4 on the 60 m and &gt;3.5 on the 10 m DB-1 columns (Table 2)</li><li>Precision was &lt;1.85% RSD and &lt;2.5% RSD for He and H2 carrier, respectively (Table 3)</li><li>Linearity was demonstrated from 10 ppm to 100,000 ppm for He and H2 carrier with R2 ranging from 0.9997 to 1.0000&nbsp;</li></ul><h5><strong>Carrier Gas Switching</strong></h5><ul><li>He and H2 carrier gases were alternated line by line in a sequence table for increased analytical efficiency and higher throughput while demonstrating the flexibility the helium conservation module provides its users while also eliminating manual changes to plumbed gases at the GC EPC Module.</li></ul><h3><strong>2.

In order to purge and trap these analytes, there needs to be an analytical trap able to trap these compounds and desorb them to the Gas Chromatograph/Mass Spectrometer (GC/MS) both accurately and efficiently. Due to the broad range of compounds on the Method 8260 list, there are many issues to take into account. Purge efficiency, molecular weight, volatility, and water are among the most problematic issues. The purge and trap concentrator and analytical trap must be able to account for all of these concerns.&nbsp;</p><p>The most commonly used analytical trap is the Vocarb® 3000 due to its ability to trap and desorb the extensive analyte list both effectively and correctly. However, the Vocarb® 3000 trap is not without its drawbacks. One of which is Bromomethane degradation in the trap over time. This application will examine the Vocarb® 3000 and a custom trap along with the optimum trap temperature parameters for the stability of Bromomethane.&nbsp;</p><h4><strong>Experimental</strong></h4><p>The purge and trap concentrator used for this study was the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/2160"><strong>EST Analytical Evolution</strong></a>. The <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/2159"><strong>Centurion Water and Soil autosampler</strong></a> equipped with the syringe option was employed as the autosampler.

The purge and trap parameters and analytical traps used for this study are listed in Tables 1 and 2 while Table 3 details the GC/MS parameters.</p><h4><strong>Conclusions</strong></h4><p>Initially, all of the traps and heating parameters used in the EST Analytical Evolution met USEPA method 8260 requirements and could be used in the laboratory. However, the custom trap and the higher temperature desorb and bake showed a lower response when compared to using a lower temperature desorb and bake. Furthermore, over time, the custom trap and higher temperature desorb and bake displayed lower recoveries of Bromomethane which could in turn affect the continuing calibration standards. The Vocarb® 3000 trap with the lower temperature desorb and bake proved to be the optimum method for sampling USEPA Method 8260 compounds. The technique met all of the method requirements and exhibited the best response and stability not only for Bromomethane but also for the rest of the extensive compound list.</p><h3><strong>3.

Furan and some alkylfurans, such as 2-methylfuran, 3-methylfuran, and 2,5-methylfuran (furan with a hydrocarbon chain attached), are found in processed food. They are generated through a variety of pathways during heat treatment of the food. Some countries have studied these compounds and concluded they are a health concern. 1) At present, no country has set permissible levels for furan or alkylfurans in food. But since they are harmful substances that are generated unintentionally during the processing of food, analyzing them is becoming increasingly important. In this Application News, the levels of furan and alkylfurans in commercially available processed food were measured.</p><h4><strong>Equipment&nbsp;</strong></h4><p>The <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=GCMS-QP2050"><strong>GCMS-QP2050</strong></a> gas chromatograph mass spectrometer has a compact design for a smaller installation footprint.
