Natural Gas Analyser C - Quick Reference Guide

<div><p><strong>During his academic career he has collected one prestigious award after another. However, he is not interested in&nbsp;awards&nbsp;and instead he seeks new interesting challenges. With a head full of ambitious ideas that have the potential to transform the way we look at chemistry, and despite his wealth of experience, he realises that his scientific journey is still at the beginning.</strong></p><p>He is as passionate about his love of coffee as he is about science. If you love it too, you might meet him in one of the cafes in Liberec. In them, and not only in them, he likes to taste different types coming from all over the world. Among his favourites are coffees from Panama, East Timor or Tanzania. "<i>My research, which involves the use of lasers to shape matter at the nanoscale, can also be linked to coffee. For example, the laser fragmentation method I use for this can also be used for cold brew, i.e. cold coffee preparation</i>," says Ondra from CXI TUL.</p><p><strong>Garbage man, president or scientist?</strong></p><p>Although science is now his passion, Ondra's journey did not necessarily have to end there. "<i>I didn't want to do research. All through high school, I heard that I should go do math, physics and nuclear research and become a professor there. In the end, I decided not to go to either faculty. Instead, based on the recommendation of the head of the research on modular nuclear reactors in Řež, I applied to study nanotechnology at TUL, with the idea that after my studies I would anchor myself in a company and enjoy a quiet non-scientific life. And the very good reputation of the local&nbsp;student houses&nbsp;helped me in my final choice of this university</i>," laughs Ondra. "<i>Interestingly, it has always proven to me that even the most seemingly trivial thing can be a great indicator to decide on something</i>."</p><p>Similarly, in the fifth grade, he chose a grammar school because of the new cafeteria, and that turned out to be the right choice. Although he didn't like the school very much, his outlook gradually changed. As a kid he wanted to be a garbage man, and a few months later he wanted to be president, mainly so he could cancel school outright. "<i>I was bored at school, the assignments were taking up my free time, so I was looking for the shortest way to solve them. I was quite a pain in the&nbsp;neck&nbsp;at times. Even the teachers took a break when I was sick,</i>" he recalls. Eventually, though, he found a passion for education. His subject became laser nanotechnology, which allows him to look at things differently.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Ondrej_Havelka_Laser_muze_zbavit_chemii_kadinek_i_zazitych_predstav_9798f8a648.jpg" alt="CXI TUL: Ondřej Havelka: Laser can get rid of the chemistry of the beakers" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CXI_TUL_Ondrej_Havelka_Laser_muze_zbavit_chemii_kadinek_i_zazitych_predstav_9798f8a648.jpg 227w," sizes="100vw" width="5463" height="3747"></p><p><strong>Laser synthesis of nanoparticles</strong></p><p>Instead of preparing nanoparticles using conventional wet chemical methods, he prepares them using a laser. And why is that? "<i>The advantage of laser-prepared nanoparticles in liquid lies mainly in their atypical internal structure. The formation of such a structure occurs because of the extremely rapid cooling during their preparation. In other words, the nanoparticles released by the laser from the solid material first take the form of hot spheres of liquid metal, which cool and solidify extremely quickly on contact with the cold liquid. Because of the speed of this process, the atoms inside the nanoparticles don't have enough time to get to places where they would feel comfortable and instead solidify in places we wouldn't expect them to. This creates defects and clusters of atoms that are otherwise unstable in the long term. This gives the nanoparticles unique properties for a number of applications - especially catalysis. We use this advantage to purify water from a variety of pollutants</i>," explains Ondra, who demonstrated the use of laser nanoparticles to purify water from oils, persistent organic substances, and antibiotics.</p><p><strong>Nanotechnology for clean water</strong></p><p>Antibiotic contamination of water has become a much-discussed problem in recent years because it threatens human health. The development of antibiotic resistance alone is already estimated to be responsible for hundreds of thousands of deaths a year. Moreover, other predictions warn that by 2050, resistance could result in up to 10 million deaths per year.</p><p>Experts from across disciplines are aware of the importance of the solution, which is why a special platform <a target="_blank" rel="noopener noreferrer" href="https://czepar.cz/">CZEPAR</a> (Czech Platform for Antibiotic Resistance) was created in the Czech Republic, of which Ondra is a member. He deals with the solution of cleaning water from antibiotics, which is complicated due to their chemical nature. This is where laser-created nanoparticles come into play. They simply break down antibiotics into simpler substances. "<i>We wanted to keep the process simple, so we developed special nanosheets that can break down antibiotics using visible light, potentially very well with sunlight</i>."</p><p>The use of nanoalloys and light overcomes the disadvantages of alternative methods for water purification such as biological removal or adsorption. Biodegradation often shows low efficiency and adsorption, on the other hand, is prone to the back-release of antibiotics when external conditions change. Nanoalloys do not have these problems. Another advantage is the ability to manipulate the nanoparticles with a conventional magnet, allowing them to be easily removed from the water after the process is complete and subsequently reused. "<i>This avoids the paradoxical scenario of removing the antibiotics but adding another potentially hazardous material to the water</i>," Ondra adds. "<i>Although the research is only at the beginning, the first results show a very promising direction for further research. We are already working on the possibility of further improvements,</i>" he concludes by discussing one of his research projects.</p><p><strong>Chemistry without beakers</strong></p><p>In addition to the application of nanoparticles for water purification, Ondra is newly involved in the actual shift in the form of laser nanotechnology. To work with nanoparticles, he stops using conventional laboratory glassware and instead uses a nanoprinter. This approach, for example, allows him to build more complex structures from the nanoparticles themselves. "<i>It's amazing to see such a structure in operation. I like to say that the laser is a tool that can rid chemistry of its cachet and of the conventional ideas about its possibilities,</i>" Ondra explains, adding: "<i>We often have very clear ideas about the shape of fields like chemistry or physics. However, the concept of fields that is only in our heads is gradually changing. This was evident, for example, at the last Nobel Prize ceremony, where two prizes were based on the topic of artificial intelligence.</i>"</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Ondrej_Havelka_Laser_muze_zbavit_chemii_kadinek_i_zazitych_predstav_2_aaef113c95.jpg" alt="CXI TUL: Ondřej Havelka: Laser can get rid of the chemistry of the beakers" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CXI_TUL_Ondrej_Havelka_Laser_muze_zbavit_chemii_kadinek_i_zazitych_predstav_2_aaef113c95.jpg 235w," sizes="100vw" width="1692" height="1125"></p><p><strong>Teaching is important</strong></p><p>Ondra has received a number of awards for his activities in the academic environment. Among them are three prestigious awards from the Minister of Education of the Czech Republic and two awards from IOP Publishing. However, he does not want to talk much about the awards. He enjoys the activities themselves. "<i>I try to make sure that everything I do contains an element of enthusiasm. I like to pass this on to others, which is why I love teaching nanotechnology and bioengineering to students. I look for ways to transform the teaching for them, to make it useful, fun and something out of the ordinary. It's great to then see the students progress year on year in what they can do</i>," he says, highlighting the importance of teaching future young scientists</p><p><strong>New challenge: Developing a new nanotechnology</strong></p><p>Ondra's dissertation defense is just around the corner. So what are his future plans? "<i>I have been offered the opportunity to lead a materials research course in Germany. I don't know yet whether it will be again at the Max Planck Institute, where I worked last year, or at one of the German universities. There are now a number of negotiations going on around that with universities in the Excellence Initiative, which is a kind of equivalent of the American Ivy League. Good laboratory facilities where research ideas can be translated into reality will be essential. If all goes well, I would like to start developing a new type of nanotechnology,</i>" he adds.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Ondrej_Havelka_Laser_muze_zbavit_chemii_kadinek_i_zazitych_predstav_3_97cb08dcb3.jpg" alt="CXI TUL: Ondřej Havelka: Laser can get rid of the chemistry of the beakers" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CXI_TUL_Ondrej_Havelka_Laser_muze_zbavit_chemii_kadinek_i_zazitych_predstav_3_97cb08dcb3.jpg 234w," sizes="100vw" width="4671" height="3106"></p></div>

Agilent Technologies: ICP-OES Quality Control of Elements in Brines Produced by Direct Lithium Extraction (DLE)</strong></h4><p><strong>Automated analysis of lithium brines using an </strong><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=ICP-OES+automation+system"><strong>Agilent ICP-OES Automation System</strong></a></p><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_icp_oes_elements_brine_direct_lithium_extraction_5994_8041en_agilent_93bdef1f77.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Direct Lithium Extraction (DLE) technology is a selective process designed to recover lithium (Li) from underground raw Li brine deposits while removing impurities.<sup>1</sup> Compared to conventional Li extraction methods, such as mining hard rock ores or using brine evaporative methods, DLE is faster, consumes less water and power, produces less waste, and requires less land. Given these process and sustainability advantages, DLE is gaining significant attention from industry, academia, investors, and environmentalists.</p><h5><strong>Agilent ICP-OES Automation System</strong></h5><p>Robust instrumentation is therefore needed for the routine elemental analysis of large numbers of brine samples. An Agilent ICP-OES Automation System comprising the Agilent <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=5900+SVDV+ICP-OES"><strong>5900 SVDV ICP-OES</strong></a>, Advanced Valve System (AVS 7), Advanced Dilution System (ADS 2), SPS 4 autosampler, and instrument software was used in this study. The Agilent <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=5800+VDV"><strong>5800 VDV ICP-OES</strong></a> is also suitable for this application.&nbsp;</p><p>The 5900 ICP-OES uses a vertical plasma torch and a solid-state radio frequency (SSRF) generator operating at 27 MHz to create a plasma with the stability needed for the routine analysis of brines. The integrated AVS 7 switching valve ensures fast analysis times and reduces instrument exposure to solids in high TDS samples.<sup>3</sup> The accessory also minimizes carryover from sodium (Na) and prevents excessive torch devitrification, greatly reducing the frequency of instrument cleaning and extending the lifespan of parts.</p><p>The samples analyzed in this study were produced using a membrane-based DLE methodology and included a wide variety of sample matrices, with target analytes typically present across a broad range of concentrations. Some key analytes, such as Li, Na, and magnesium (Mg), are particularly important to quantify as they directly impact the efficiency of the DLE process.&nbsp;</p><p>To account for the different compositions and densities of the DLE samples, the ADS 2 was used to prepare calibration standards across a wide analytical range and to dilute the samples before analysis.<sup>4</sup> Both processes can be labor-intensive and time-consuming when performed by an analyst, as well as being potential sources of contamination and errors. The implementation of advanced autodilution technology for ICP-OES enhances sample turnaround time and minimizes the risk of human errors, while ensuring accurate results.</p><h5><strong>Conclusion</strong></h5><p>An Agilent ICP-OES Automation System comprising the Agilent 5900 SVDV ICP-OES, AVS 7, ADS 2, SPS 4 autosampler, and ICP Expert Pro instrument software was used to analyze 12 elements in real brine samples. The raw, tail (Li-free), and Li concentrate brine samples were sourced from before and after processing using a membrane-based Direct Lithium Extraction (DLE) technique. All samples were analyzed using a single method in a single run.</p><p>The IntelliQuant Screening method development tool within the software was used to set the calibration range for the analytes and to select the best analyte wavelengths. The use of the ICP-OES Automation System provided productivity and performance benefits for the brine application including:</p><ul><li>Automatic calibration. Completely automated calibration from three stock solutions removed the need to manually prepare standards to cover the wide and varying concentration range of analytes in the brines.</li><li>Prescriptive dilution. The ADS 2 was used to automatically dilute all three of the Li brine samples 50 times, so that the samples could be measured in a single run.</li><li>Reactive dilution. The ADS 2 automatically diluted the Li concentrate brine sample 200x in response to the concentration of Li exceeding the calibration range before remeasurement.</li><li>The ADS 2 also performed reactive dilutions on the raw brine (150x) and the tail brine (250x) to quantify Na.</li><li>Results summary report. The software selected the best measurement results to display from the available reactive dilution remeasurement results. It allowed for straightforward data viewing and reduced the amount of time required for manual data processing.</li><li>The AVS 7 minimized the exposure of the torch, nebulizer, and pump tubes to the high matrix samples. It also worked seamlessly with the ADS 2 to improve sample turnaround times.</li></ul><h4><strong>2. Bruker: IR-Spectroscopic Analysis of Polymer Fillers and Compatibilizers</strong></h4><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/AN_M104_Polymer_filler_ALPHA_II_EN_dce568f395.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Many of today’s plastics are multi component systems with multiple constituents like different polymers, fillers, plasticizers and compatibilizers. By systematic selection and blending of these constituents in appropriate mixture ratios tailor made substances with optimized material properties can be made. An important topic for quality control and analytical purposes is the identification and quantification of the individual components present in such plastics.&nbsp;</p><p>Fourier transform infrared (FT-IR) spectroscopy is one of the fastest and most accurate methods for the analysis and quality control of polymers. High quality IR spectra can be recorded in a few seconds; usually there is no need for sample preparation or costs for expensive consumables. Within only a minute FT-IR spectroscopy allows to verify that a given product is within its specification or to quantify one or more of its constituents.</p><h5><strong>Measurement approach</strong></h5><p>Nowadays, quality control and routine analysis using IR spectroscopy is mainly performed applying the ATR (Attenuated Total Reflection) technique. As there is virtually no sample preparation required ATR is much more comfortable to use than the conventional transmission mode. For the analysis the sample has to be pressed on the ATR-crystal, which is the measurement interface. From the ATR-crystal, the IR radiation penetrates slightly (a few microns) into the sample surface. The IR detector of the FT-IR spectrometer can then measure the absorbance resulting from the sample. The ATR-technique can be applied for almost all types of samples (e.g. solids, liquids, powders, pastes, pellets, slurries, fibres etc.). The analysis takes less than a minute, including sampling, measurement and data evaluation. By using ATR, it is even possible to differentiate between the top layers of a polymer laminate, which cannot be achieved in transmission mode.</p><h5><strong>Instrumentation</strong></h5><p>The very compact <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=8&amp;search=Alpha+II"><strong>ALPHA II FT-IR</strong></a> spectrometer with the high pressure Platinum diamond ATR-module is a robust and affordable system that is very easy to operate. Diamond is a very hard-wearing, chemically inert and therefore ideal material for the analysis of a wide range of samples. In the platinum ATR-module the diamond is brazed into tungsten carbide. This extremely robust design allows the application of very high pressure so that even the hardest plastics can be measured. For the measurement of highly absorbing dark samples (e.g. black polymers) and thin layers an ATR-material with a high refractive index is required to limit the penetration depth of the IR-light into the sample. Therefore the Platinum ATR module can be equipped with a germanium (nGe = 4.0) crystal plate. To provide the user an unobstructed access to the sampling area, the pressure applicator can be rotated by 360°. The software is very intuitive and a software wizard guides the user through the analysis procedure.</p><h5><strong>Summary</strong></h5><p>The combination of Bruker Optics compact and robust FT-IR spectrometer ALPHA II with a high pressure diamond ATR unit is an ideal tool to analyze polymers, fillers and polymeradditives. The system allows quantifying single components in complex mixtures. The setup of new methods even for chemically similar polymers is quick and straightforward. A very intuitive work flow allows even spectroscopically inexperienced users to perform the analysis.<br>Altogether the ALPHA II is perfectly suited for the identification of fillers, the quantification of mixture components and the quality control of polymers.</p><h4><strong>3. Metrohm: Moisture content and rheology determination of fluorinated polyolefins using NIRS</strong></h4><p><strong>Moisture and melt flow rate analysis results within seconds</strong></p><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_nir_119_download_ec261a206c.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Ethylene tetrafluoroethylene (ETFE) is a partially fluorinated copolymer of ethylene and tetrafluoroethylene. ETFE is a melt processable polymer, designed to have high corrosion resistance and strength over a wide temperature range. Some key quality parameters that should be monitored during the production of fluorinated polyolefins are melt flow rate (MFR) and moisture content. The measurement of these parameters usually involves using chemicals and can be time-consuming. Nearinfrared spectroscopy (NIRS) offers users rapid and reliable prediction of key quality parameters in ETFE without any sample preparation or cleaning procedures.&nbsp;</p><h5><strong>Experimental equipment</strong></h5><p>273 ETFE pellet samples with varying MFR and moisture content were measured on a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=220&amp;search=NIR"><strong>Metrohm nearinfrared spectroscopic analyzer</strong></a> in reflection mode. All measurements were performed in rotation using a large sample cup to reduce the stray light effect caused by varying particle sizes. An overlay of the sample spectra is displayed in Figure 1.</p><h5><strong>Conclusion</strong></h5><p>This Application Note demonstrates the feasibility to determine mechanical properties and perform moisture analysis in fluorinated polyolefins like ETFE using NIRS. In comparison to the standard analytical methods (Table 1), quality control with NIR spectroscopy shows obvious advantages regarding the analysis time. In addition, the sample handling with near-infrared spectroscopy is easier to perform and safer since no chemicals are needed.</p><h4><strong>4.

By composition, copper alloys are classified as the 1000 seriesto the 7000 series. Energy dispersive X-ray fluorescence spectrometers (EDXRF) are widely used in applications such as receiving inspections of recycled materials, taking advantage of their excellent operability and simple sample handling, but high-accuracy wavelength dispersive X-ray fluorescence spectrometers (WDXRF) are used mainly in metal manufacturing processes. However, as a result of improvement in the quantitative accuracy of EDXRF in recent years, a wider range of applications, such as use in manufacturing processes, is expected in the future.

In the quantitative analysis by the calibration curve method, repeatability was evaluated, showing that results with high reliability can be obtained. The qualitative/quantitative analysis by the FP method also showed that samples can be differentiated easily by using the matching search function of the EDX-7200. Thus, the EDX-7200 offers a combination of merits. In addition to excellent analytical performance and a small installation footprint, there is no need cooling water or other auxiliary equipment, there are few limitations on the sample shape, and highly accurate analysis of samples even in their original shape is possible. Based on these advantages, It is expected that EDX-7200 will be widely used to replace analysis using WDXRF.</p><h4><strong>5.

Agilent Technologies: Analysis of 65 Volatile Organic Compounds in Ambient Air by Canister Sampling Using an Agilent </strong><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?manufacturerItems=1&amp;search=8890%2F5977"><strong>8890/5977</strong></a><strong> GC/MSD</strong></h4><h5><strong>A method using both scan and SIM mode that fully meets the requirements in the HJ 759-2023 standard</strong></h5><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_voc_air_gc_msd_5994_7723en_agilent_4b88e40417.pdf"><strong>Full PDF for download</strong></a></li></ul><p>This application note introduces the use of a canister for gas sampling. Samples were introduced into an Agilent 8890 gas chromatograph (GC) with an Agilent 5977 single quadrupole mass selective detector (MSD) and the Markes Multi-Gas thermal desorption (TD), to analyze volatile organic compounds (VOCs) in the atmosphere or in semiconductor cleanrooms. The results of linearity, reproducibility, and detection limit fully met the requirements of the China method HJ759-2023. This method is widely used as a reference both in environmental laboratories and semiconductor cleanrooms. The linear correlation coefficient for all 65 compounds was greater than 0.991, with 86% of compounds having a value greater than 0.999. The results of reproducibility in scan mode varied between 0.3 to 6.8%, while results in SIM mode varied between 1.1 to 6.7%. The sampling volume was 300 mL, which resulted in detection limits of 0.013 to 0.113 nmol/mol for scan mode and 0.002 to 0.013 nmol/mol for SIM mode.&nbsp;</p><h4><strong>Experimental</strong></h4><p>This study was performed on an 8890 GC coupled to a 5977 single quadrupole GC/MSD with an electron ionization (EI) source. A Markes Multi-Gas thermal desorption sample introduction and preconcentration system was used and included three modules:</p><ul><li>CIA Advantage-xr (CIA): canister autosampler</li><li>Kori-xr: water removal module</li><li>Unity-xr: thermal desorption instrument</li></ul><p>First, three internal standards (ISTDs) were introduced into the Unity trap by CIA. Then, the sample was passed through a heated transfer line through the CIA Advantage<br>into the Kori for water removal. Finally, the sample flowed into the focusing cold trap of the Unity for preconcentration. Eventually, the Unity trap was desorbed at high temperature, and the 65 VOCs and three ISTDs all entered the GC/MSD for analysis. Figure 1 shows the flow path of the combined system.&nbsp;</p><h4><strong>Conclusion</strong></h4><p>An Agilent 8890/5977 GC/MSD system, equipped with a Multi-Gas CIA Advantage-xr TD provides a robust analytical procedure for the analysis of 65 VOCs in ambient air. This system offers a highly efficient and highly sensitive solution for the simultaneous analysis of multiple VOCs in both atmospheric quality monitoring laboratories and semiconductor cleanrooms. Based on different application requirements, users can choose to collect data in scan or SIM mode, demonstrating the flexibility of Agilent instruments. Excellent analytical performance has been achieved based on this system both in scan and SIM mode, which fully meets the requirements detailed in method HJ 759-2023.</p><h4><strong>2. Knauer: GPC vs. SPE and subsequent determination of polycyclic aromatic hydrocarbons using GC/MS</strong></h4><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/VEV_0081_Comparison_of_GPC_and_SPE_purification_methods_of_sludge_samples_FINAL_web_376100390f.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants generated primarily during the incomplete combustion of organic materials. The removal of PAHs from the atmosphere by dry and wet deposition processes are strongly influenced by their gas/particle partitioning. Atmospheric deposition is a major source for PAHs in soil [1] which can be determined by various extraction and purification processes, subsequently detected by a GC/MS using the reference method UNI EN 15527. Our main purpose is to demonstrate that the purification of environmental matrix with high organic component using the gel permeation chromatography purification (AZURA GPC Cleanup, FS conditioned resins CHEX/DCM), compared to a SPE purification, allows are well-defined separation time of the analytes and it can provide narrow bands without their physical chemical interaction with the column, resulting in less chance of loss of analytes [2]. This differs from other separation techniques which depend upon chemical or physical interactions to separate analytes [3].</p><h4><strong>Conclusion</strong></h4><p>The GPC cleanup procedure of mud sludge samples prior analysis of PAHs with GC/MS technique is a good alternative to SPE purification steps. Advantages like better S/N ratios and third mass identification are obvious. The automatization of the GPC Cleanup using AZURA GPC Cleanup system yields high efficiency of the application.</p><h4><strong>3.

They are feared to have an impact on ocean pollution and ecosystems. Against this backdrop, surveys and studies on MPs in surface waters such as oceans, rivers, lakes and marshes are being conducted worldwide. Fourier Transform Infrared Spectrophotometer (FTIR) is often used for material analysis of MPs. ASTM recently published the D8401-24 standard test method for the qualitative and quantitative determination of MPs in water that uses a pyrolysis gas chromatograph mass spectrometer (Py-GC-MS). In this application news, a sample taken from a river was pretreated and analyzed for MPs using FTIR and Py-GC-MS.</p><h4><strong>Conclusion</strong></h4><p>Samples collected from river water were automatically pretreated using MAP-100, and the MPs materials were then analyzed by FTIR and Py-GC-MS. PP, PE and EVA were detected in both instruments, indicating that PP and PE are the main components (Fig. 8). Using an FTIR, individual qualitative results can be obtained easily, and the number ratios and densities can be calculated. Py-GC-MS also provides a more accurate massto material ratio (%). The system supports screening methods that take advantage of the features of each instrument, from preparation to analysis of MPs.</p>
