Agilent Technologies: Automated Analysis of Foods by ICP-QQQ with Discrete Sampling and Autodilution</h3>Fast, accurate AOAC compliant food analysis using the <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/icpms/library?mainauthorItems=10&amp;search=9500">Agilent 9500 ICP-QQQ</a> with AVS MS and ADS 2&nbsp;<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/pdf/an_automated_food_analysis_9500_icp_qqq_5994_9095en_agilent_e5869385b0.pdf">Full PDF for download</a>&nbsp;</li></ul>Manufacturers and regulatory bodies, including state and federal governments, have an obligation to ensure that food is safe for human consumption. To protect public health, manufacturers and producers follow rigorous testing procedures, such as AOAC Official Method 2015.01 for the analysis of heavy metals in foods using ICP-MS.1 In recent years, global initiatives have sought to strengthen existing regulations and further reduce contaminant limits, as shown by the US Food and Drug Administration’s Closer to Zero program. Meeting these increasingly stringent targets depends on analytical instruments capable of delivering higher performance, improved sensitivity, and greater accuracy. At the same time, food testing laboratories are actively pursuing greater productivity and workflow efficiency to keep pace with evolving analytical demands.To support these goals, the <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/icpms/library?mainauthorItems=10&amp;search=9500">Agilent 9500 Triple Quadrupole ICP-MS</a> (ICP-QQQ) and Advanced Dilution System (ADS 2) combine seamlessly to streamline methods, improve productivity, and deliver high-quality results. Using the 9500 instrument’s unique Dual-Cell System (DCS) with Advanced Helium Mode (AHM) and Air cell mode enables effective removal of polyatomic and doubly charged interferences and enhances low-mass sensitivity.2,3 In addition, the ADS 2 simplifies sample preparation by creating calibration standards from a stock solution, pre-diluting samples before analysis, and reactively diluting any samples that exceed the calibration range. Together, these technologies support faster, more reliable delivery of accurate results.&nbsp;In this study, various standard reference materials (SRMs) were selected to represent different sample types that may be analyzed in food testing laboratories and to validate the method. As these laboratories often require high productivity, the 9500 ICP-QQQ configuration and analytical method were optimized to maximize sample throughput. The performance of the method was evaluated according to criteria set out in the AOAC 2015.01 method.<h4>Conclusion&nbsp;</h4>The Agilent 9500 ICP-QQQ with Dual-Cell System (DCS) successfully quantified a broad range of metals in diverse food matrices in accordance with an AOAC standard method. Most elements were measured in AHM, while As and Se were accurately determined at trace levels in Air cell mode using ambient air to eliminate severe doubly charged REE interferences. AHM mode effectively suppressed polyatomic interferences such as NaAr on Cu, even in samples such as NIST 1573a Tomato Leaves, where Na is present at more than 20 times the concentration of Cu.&nbsp;Together, the two DCS gas modes provided comprehensive interference control for routine food analysis, as demonstrated by recoveries of certified elements within ±25% for the food SRMs.&nbsp;Compared to single-quadrupole ICP-MS, DCS operation in both modes reduced analysis time by about 30 seconds per sample. Automation using the Agilent AVS MS discrete sampling accessory, SPS 4 autosampler, and ADS 2 autodilutor further improved productivity and delivered reliable results, including:&nbsp;<ul><li>Detection limits for As, Cd, Pb, and Hg well below the LOQs reported in AOAC 2015.01&nbsp;</li><li>Effective removal of REE2+ interferences on As and Se&nbsp;</li><li>Over 98% Lu recoveries across all SRMs, demonstrating excellent preservation of volatile elements throughout the analysis&nbsp;</li><li>Stable operation over five hours, maintaining CCV and ISTD recoveries within AOAC limits&nbsp;</li></ul>The 9500 ICP-QQQ enables high-throughput, AOAC-compliant food analysis by controlling interferences with AHM and Air cell mode, ideal for labs that need speed, reliability, and accuracy.<h3>2. LECO: Determination of Total Carbon (TC) and Total Organic Carbon (TOC) in Soil by Acid Digestion and Combustion</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/pdf/832_TC_TOC_SOIL_ACID_DIGESTION_COMBUSTION_203_821_679_e5b4978a69.pdf">Full PDF for download</a></li></ul>Total organic carbon (TOC) determination in soil is a widely used method for evaluating soil quality in agriculture. TOC levels are a key indicator of soil vitality, fertility, and capacity for atmospheric carbon sequestration. TOC represents the carbon stored in soil organic matter, which plays a vital role in supporting microbial life, enhancing nutrient availability, and improving soil structure. These benefits translate directly into better water retention, reduced erosion, and more resilient crops—key factors for regenerative systems focused on ecosystem restoration and productivity. TOC levels can also be used to monitor the effectiveness of sustainable practices like crop rotation, cover cropping, reduced tillage, and the addition of organic matter such as manure and compost. Measuring soil TOC levels helps growers optimize the use of soil amendments like compost and manure to increase organic matter without over-application.<h4>Instrument Model and Configuration&nbsp;</h4>The <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/products/1883">LECO C832</a> is a carbon determinator that utilizes hightemperature combustion in a whole oxygen environment to analyze a wide range of sample types. It features a ceramic combustion furnace in a horizontal orientation designed to analyze macro sample masses. Analysis begins when a sample is weighed into a ceramic combustion boat and inserted into the furnace where combustion is initiated under a controlled flow of oxygen. After a preset time, additional oxygen is applied directly above the sample using a ceramic lance to accelerate and complete the combustion process. The gases are swept from the furnace and passed through anhydrone for the removal of moisture and are then carried to a nondispersive infrared (NDIR) cell for detection of carbon as CO2.<h4>Typical Results&nbsp;</h4>For soils containing up to 5 % carbon, a linear, force through origin calibration using LECO synthetic carbon reference materials is recommended. For soils containing more than 5 % carbon, a linear, full regression calibration using LECO synthetic carbon and calcium carbonate reference materials is recommended.<h3>3. Shimadzu: Determination of More Than 25 Nutritional, Essential and Toxic Elements in Whole Blood by ICP-MS Using Alkaline Dilution</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/pdf/an_05_sca_116_014_en_5fc2b521ce.pdf">Full PDF for download</a></li></ul><h5>User Benefits</h5><ul><li>Offering gas switching times &lt;5 sec and ProActive Rinsing function, short sample cycle times can be achieved&nbsp;</li><li>Using whole blood calibrators and control samples in research labs simplifies working routines&nbsp;</li><li>Alkaline media drastically improves washout capabilities for mercury and ensures proper sample stabilization compared to acidic media</li></ul>Inductively coupled plasma mass spectrometry (ICP-MS) like <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/icpms/library?mainauthorItems=1&amp;search=2050">Shimadzu ICPMS-2050</a> offers ultra-low detection limits and fast multi-element capability required for reliable high throughput measurement of nutritional, essential, and toxic elementsin various complex biological samples.&nbsp;While urine has been widely used to monitor elemental excretion, blood serum represents the protein-free fraction of circulating blood. Whole blood, however, contains both cellular and extracellular components, enabling a more integrated assessment of an individual’s nutritional status and exposure to potentially toxic metals than either urine or serum alone. Accordingly, whole-blood ICP-MS analysis is well suited for research applications such as nutritional assessment, toxicology, and biomonitoring studies.<h4>Conclusion</h4>The ICPMS-2050 LF was specifically configured for robust small volume analysis while reducing carry over, sample cycle times and environmental contamination impacts while being capable of successfully addressing several kind of possibly interference providing most accurate and reliable results.&nbsp;The collision- and reaction cell performs efficiently with flowrates of helium and hydrogen in low levels of 6-7mL/min. At the same time, the method uses the well established Minitorch plasma system, allowing lowest argon consumption while reducing power consumption, which makes it exceptionally cost-effective without compromising performance characteristics.&nbsp;LabSolutions ICPMS software allows to easily control the device, consumable lifetime, QC-recoveries and internal standard stability. Furthermore, features like ProActive Rinsing and Extended Rinsing speed up the method while reducing carryover risks.<h3>4.

News from LabRulezICPMS Library - Week 39, 2026

Acne is one of the most common skin conditions. It affects up to 85% of people during adolescence and, for many, persists into adulthood. Beyond its physical symptoms, it can also significantly affect self-confidence. Treatment often takes time, and some commonly used products can dry out or irritate the skin. Researchers at CEITEC Brno University of Technology (BUT) have developed specially modified cellulose microfibres that effectively inhibited acne-causing bacteria in laboratory tests. The fibres can be used in face masks. These findings could pave the way for new approaches to treating&nbsp;acne-prone skin.The material consists of cellulose acetate microfibres enriched with zinc oxide and subsequently treated with oxygen plasma. The zinc oxide is then gradually released into the skin, where its antibacterial action limits the growth of bacteria associated with acne. Unlike conventional products, the active ingredient is incorporated directly into the fibres and released gradually, allowing for a longer-lasting effect.“The fibres retain high efficacy without any of the additives commonly found in commercial products. The material contains exactly what is needed to combat acne effectively, with no unnecessary ingredients. Our research showed that the fibres retain their antibacterial effect for at least a year after treatment,” says Martina Říhová of the Advanced Low-Dimensional Nanomaterials research group at CEITEC BUT, who led the research. This demonstrated long-term effect opens the door to commercial applications.In the future, the same principle could also be used to treat other skin conditions complicated by bacterial infections, such as atopic dermatitis. The fibres could be incorporated not only into face masks for acne treatment but also into patches for smaller affected areas or dressings suitable for larger areas.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_K_lecbe_akne_muze_pomoci_technologie_inspirovana_vyrobou_cukrove_vaty_2_1be8944b43.jpeg" alt="CEITEC BUT/Jakub Rozboud: Technology Inspired by Cotton Candy Could Help Treat Acne: Martina Říhová from CEITEC BUT during face skin analysis." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_K_lecbe_akne_muze_pomoci_technologie_inspirovana_vyrobou_cukrove_vaty_2_1be8944b43.jpeg 235w," sizes="100vw" width="1600" height="1067"><h3>Fibres Made Much Like Cotton Candy</h3>The researchers produced the microscopic fibres using centrifugal spinning. The same physical principle is used to make cotton candy, but in this case, fine polymer fibres are formed instead of sugar strands.The breakthrough came from combining a method called Vapour Phase Infiltration, which enriched the fibres with zinc oxide, with subsequent oxygen plasma treatment. This treatment slightly disrupts the surface of the fibres, allowing the active substances to be released upon contact with water.“We were the first in the world to demonstrate this procedure using cellulose acetate fibres,” notes Martina, who has been researching acne and its treatment for seven years. She and her colleagues published their <a target="_blank" rel="noopener noreferrer" href="https://www.researchgate.net/publication/403127590_Cellulose_Acetate_Fibers_With_Infiltrated_ZnO_Nanocrystals_Activation_of_Antibacterial_Properties_Against_Acne_vulgaris_by_Oxygen_Plasma_Treatment">findings</a> in Small, one of the world’s leading scientific journals focusing on nanomaterials and nanotechnology.<h3>Researchers from Brno and Spain Joined Forces</h3>Several research teams from different institutions contributed to the material’s development. “Our team, led by Jan Macák, was responsible for preparing the fibres. We then took them to San Sebastián in Spain, to Mato Knez’s team at nanoGUNE, where they carried out the vapour phase infiltration. Next, Lenka Zajíčková’s team at CEITEC BUT treated the fibres with oxygen plasma. Finally, Zbyněk Heger’s team at the Department of Chemistry and Biochemistry at Mendel University conducted the antibacterial testing,” says Martina Říhová, describing the collaboration.The research took more than a year. Before the new material can enter routine use, it will need to undergo further biological testing, followed by clinical trials to verify its safety and effectiveness in treating patients.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_K_lecbe_akne_muze_pomoci_technologie_inspirovana_vyrobou_cukrove_vaty_3_b21c60ae29.jpeg" alt="CEITEC BUT/Jakub Rozboud: Technology Inspired by Cotton Candy Could Help Treat Acne: Martina Říhová's microfibres developped for acne treatment." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_K_lecbe_akne_muze_pomoci_technologie_inspirovana_vyrobou_cukrove_vaty_3_b21c60ae29.jpeg 235w," sizes="100vw" width="1600" height="1067"><blockquote><h4>The original article</h4><h4><a target="_blank" rel="noopener noreferrer" href="https://www.researchgate.net/publication/403127590_Cellulose_Acetate_Fibers_With_Infiltrated_ZnO_Nanocrystals_Activation_of_Antibacterial_Properties_Against_Acne_vulgaris_by_Oxygen_Plasma_Treatment">Cellulose Acetate Fibers With Infiltrated ZnO Nanocrystals: Activation of Antibacterial Properties Against Acne vulgaris by Oxygen Plasma Treatment</a></h4>Martina Rihova, Denisa Fenclova, Pavan Kumar Chennam, Aniket Mukherjee, David Pavlinak, Susan Azpeitia, Kristyna Cihalova, Miloslav Pouzar, Kaushik Baishya, Lenka Zajíčková, Zbynek Heger, Mato Knez, Jan M.

The antibacterial effect (through Zn²⁺ release) was activated upon oxygen plasma treatment. CA fibers (fiber diameter ≈ 2 µm) were produced via centrifugal spinning, followed by ZnO infiltration (up to 8 wt% of Zn content) using Vapor Phase Infiltration (VPI) with varying deposition cycles. As CA fibers are naturally hydrophobic, oxygen plasma treatment was applied to turn them hydrophilic and to improve skin wetting. The combination of these steps is presented for the first time.Plasma treatment introduced oxygen‐containing functional groups on the CA surface, significantly improving wettability. Scanning electron microscopy analyses of treated fibers showed no morphological damage. Detailed characterization (using X‐ray photoelectron spectroscopy, Raman spectroscopy, energy dispersive X‐ray fluorescence, X‐ray diffraction, tranmission electron microscopy) focused on fibers with 32 and 128 VPI cycles, revealed that plasma partially oxidized and etched the surface, affecting the ZnO distribution.Plasma‐modified fibers, unlike untreated ones, exhibited antibacterial activity against AV‐causing bacteria (Cutibacterium acnes and Staphylococcus epidermidis), creating significant inhibition zones (up to 5 mm), demonstrating their potential as promising therapeutic modality. Overall, plasma treatment enabled effective surface functionalization, producing antibacterial fibers with enhanced surface properties suitable for application in AV management.

Proper care and maintenance of HPLC columns are essential for getting accurate results and saving on replacement costs. Extending the HPLC column life not only ensures consistent performance but also reduces downtime and the need for frequent replacements.Routine maintenance is equally essential for sustaining column functionality. Correct handling of the column is paramount, ensuring strict compliance with the manufacturer’s specifications regarding pressure, pH, flow rate, and temperature.In the next section, we will explore these best practices in greater detail, offering further guidance on essential HPLC column maintenance strategies. Whether you’re working in a high-throughput lab, or conducting occasional analyses, these strategies will help you get the most out of your <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/products?category=48&amp;manufacturerItems=50">HPLC columns</a>.<h3>Essential Guidelines for Extending HPLC Column Life</h3>By adopting these simple yet effective practices, you can greatly extend the HPLC column life while ensuring reliable, high-quality results in your analyses.<h4>Proper Column Handling</h4>HPLC columns should be handled with care to prevent physical damage or shock. The pump should not be started at high flow rates; instead, the flow rate should be gradually increased over several minutes. A pump pressure limit should be set to protect the column from over pressuring, as sudden pressure changes can lead to voids, negatively affecting the column’s performance.<h4>HPLC Column Conditioning and Equilibration</h4>Conditioning is a critical step for preparing a new or stored HPLC column by replacing the storage solvent with the desired mobile phase. Care must be taken to avoid introducing immiscible solvent mixtures into the column. Universally miscible solvents such as THF (tetrahydrofuran) or IPA (isopropyl alcohol) can be useful for this process when moving from normal phase to reversed phase solvent systems. Care must also be taken to ensure that solvents that may be damaging to a specific stationary phase are avoided.For example, if a reversed-phase column experiences phase collapse due to 100% aqueous mobile phases, it should be reactivated. This process involves running 100% acetonitrile at a high flow rate and a temperature as high as 60°C. It is essential to ensure no solid buffers precipitate from residual solvents. Depending on the column condition, between 50 and 100 column volumes are needed for complete reactivation and equilibration, restoring the column’s efficiency for future use.<h4>Optimizing Operating Conditions</h4>Optimizing operating conditions is paramount to enhancing HPLC column efficiency and prolonging their operational lifespan. A fundamental aspect of this is strict adherence to the manufacturer’s recommended temperature, pH and pressure parameters.Deviating from these limits, particularly by operating at elevated temperatures, can significantly hasten the degradation of the stationary phase and hardware, thereby compromising overall performance. Elevated temperatures can also narrow the pH operating range, exacerbating the risk of column degradation through phenomena such as peak broadening or diminished efficiency.Effective pressure management is equally crucial. Sudden pressure surges or mechanical shocks can result in bed voiding, leading to poor chromatographic performance, such as split peaks and reduced separation efficiency. Gradual ramping of flow and pressure, implemented each time the column is initiated, mitigates these risks. Many modern HPLC systems are equipped with automated flow-pressure ramping capabilities, ensuring smoother transitions and reducing the potential for column damage.In addition, vigilant monitoring of the mobile phase's pH is vital to the maintenance of HPLC column integrity. Deviations from the optimal pH range can cause significant harm to the stationary phase. For instance, leads to ligand hydrolysis which leads to a loss of stationary phase functionality and diminished column performance over time. High pH can lead to silica degradation. This weakens the silica structure, causing particle dissolution, void formation, and loss of column efficiency. Maintaining the pH within optimal boundaries is essential for preserving the column’s structural integrity and ensuring consistent chromatographic performance.Furthermore, incorporating inline filters and guard columns into the system serves as a proactive measure to prevent particulates and harsh sample matrices from damaging the analytical column. These preventive tools significantly enhance operational conditions and safeguard the column from contamination, ultimately contributing to extended HPLC column lifetime and reliable performance.<h4>Regular Column Maintenance</h4>Effective routine maintenance is paramount to extending the HPLC column lifetime and ensuring the consistent performance of HPLC columns. A critical aspect of this maintenance is the thorough washing of the column after each use to eliminate residual sample components and mobile phase contaminants.The cleaning process generally involves performing an isocratic or gradient wash using a solvent system similar to the one previously used on the column but substituting the buffer with HPLC-grade water. This helps effectively remove any residual buffer components from the column. This meticulous cleaning process is vital to preventing the accumulation of impurities that could compromise the stationary phase and lead to decreased efficiency over time.Post-cleaning, it is imperative to end-cap the column before storage to prevent the stationary phase from drying out, a condition that can negatively impact the column’s future performance. Proper capping or sealing ensures that the column remains in optimal condition, safeguarding its structural integrity and readiness for subsequent analyses.Additionally, utilizing an older HPLC system as a dedicated wash station can further streamline maintenance practices, freeing up live systems for active use. Consistently adhering to a rigorous cleaning and storage regimen not only enhances the longevity of HPLC columns but also guarantees the delivery of precise and reliable analytical results.For severe contamination or pressure buildup, backflushing may be necessary to dislodge tightly bound contaminants. However, backflushing should only be performed when absolutely necessary, as it can stress the column packing material. It is essential to consult the manufacturer’s instructions before attempting this method.

Environmental matrices often present challenging interferences that may either be plasma or sample based.
Reduction of these interferences using kinetic energy discrimination and/or collisional dissociation have been proven to be effective using single quad ICP-MS using helium as the cell gas, however, reactive gasses can be very effective in either shifting the interference away from the analyte of interest, or shifting the analyte to a new mass, away from the associated polyatomic interference.
Using a reactive gas on a single quad ICP-MS risks creating undesired polyatomic interferences in the collision/reaction cell on other target analyte masses. By utilizing a quadrupole with single amu resolution before the collision/reaction cell, only the target analyte and associated interferences of the same mass enter the cell, giving the analyst ultimate control of the reaction products for a given analyte and associated interference. The optimization of reaction cell technology, combined with single unit mass resolution allows for more precise measurement of analytes in complex matrices, while also enjoying lower detection limits with tighter precision and improved accuracy. As regulatory detection limits become increasingly lower for environmental matrices, triple quadrupole ICP-MS/MS systems with single unit mass resolution technology has proven to be a superior approach for complex sample matrices.

Techniques and tools for improved wash out of “sticky” elements, such as B, Tl, and Hg, on an Agilent ICP-MS will be discussed.
An understanding where the individual elements stick in the instrument aids in the chemistry and the sequence of rinse solutions used for their removal. Use of the Pre-emptive rinse and Intelligent Rinse features within the MassHunter software greatly improve washout of these sticky elements. Features and setup of an Integrated Sample Introduction System (ISIS) also reduce carry over of these elements. Eliminating contamination increases the probability that accurate sample results can be obtained. Sources of common lab contaminants and methods used for their elimination will also be discussed. A semi-Cool plasma technique may be discussed to demonstrate how to calibrate and obtain somewhat lower levels of alkali metals in the presence of their interferences.
