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.

For many scientists and lab managers, the real bottleneck isn’t the instrument—it’s the manual, time-consuming steps required to keep workflows moving and data processing on track. That’s where Thermo Scientific Chromeleon software comes in.</p><h3><strong>Why GC-MS workflows can be a headache</strong></h3><p>Even with state-of-the-art hardware, GC-MS workflows demand attention. Routine maintenance—like column trimming, source cleaning, and inlet checks—must be tracked and managed. Meanwhile, retention time shifts can throw off compound detection, forcing analysts to manually correct and realign data.</p><p>And when it comes to data review, it’s easy to lose hours scrolling through chromatograms to check integrations and flag anomalies. It slows down decision-making and is tedious and can be prone to error.</p><h3><strong>Chromeleon software: Smarter software for GC-MS success</strong></h3><p><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/76"><strong>Chromeleon software</strong></a> enhances and brings effortless usability to your GC-MS system by bringing efficiency, automation, and visibility into your operations.
