MDCW / Arizona State University: Identifying Non-Biological Variance in Untargeted Analysis in Breath VOCs</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/P_8_Zabin_7786c8003b.pdf">Full PDF for download</a></li></ul><section><div><div><div><div><div><div>When performing untargeted analyses for breath biomarker discovery, the goal is to identify biological signals in the breath chemistry that can help detect disease states, probe microbial interactions, and track environmental exposures. However, untargeted metabolomics and downstream data analysis workflows are vulnerable to signal contamination by non-biological variance associated with sample collection and handling and instrumental drift, which can obscure meaningful biological patterns.&nbsp;<h4>Objective/Aims</h4>The goal of this study is to identify and quantify non-biological variance in untargeted volatile metabolomics arising from sample collection procedures and instrumental drift.<h4>Methods</h4>Breath samples were collected and transferred onto Thermal Desorption Tubes (TDTs) in technical duplicates. TDTs were stored at 4˚C and analyzed using two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (<a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/37">GC×GC– TOFMS</a>).<h4>Conclusions</h4>Instrument drift and other non-biological factors can strongly affect metabolomics data. Consistent, timedependent patterns of dissimilarity highlight the need to identify and control these sources of variance to ensure reliable biomarker discovery.<h3>2. Shimadzu: Analysis of Volatile PFAS in Textiles Using <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=GCMS-TQ8040+RX">GCMS-TQ8040 RX</a> with MMI</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01257_en_beb993613a.pdf">Full PDF for download</a></li></ul><h4>User benefits</h4><ul><li>Using the GCMS-TQ8040 RX and the Multi-Mode Injection Unit (MMI), 12 volatile PFAS including compounds listed in EN 17681-2, can be analyzed at the ppb level without preconcentration.</li><li>The spike recovery test shows good percentage recoveries of all compounds (80–120 %) that are at or below the EU Persistent Organic Pollutants (POPs) threshold limit (25 ppb)</li></ul>Per- and polyfluoroalkyl substances (PFAS) are used in textile products because of their useful properties, such as heat resistance and water repellency. However, PFAS are also extremely stable substances that resist degradation and accumulate in the environment, which has led to concerns about their effects on humans. Since eliminating sources of PFAS is essential to prevent them from accumulating in the environment and in living organisms, many countries are passing laws that restrict the production, distribution, and use of PFAS in products. For example, the EU POPs Regulation sets a permitted threshold of up to 0.025 mg/kg (25 ppb) for certain PFAS (including PFOA, PFOS, and PFHxS) in substances, mixtures, or articles1) . EN 17681 defines standard test methods for PFAS analysis in textiles2),3) .&nbsp;In a previous <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01108_en_e04fe25939.pdf">Application News, No. 01-01108</a>, an example of analyzing volatile and nonvolatile PFAS in textiles using LC/MS/MS and GC/MS/MS based on this standard was introduced. This study shows an example of trace analysis of volatile PFAS (Table1) in textiles using the newly developed GCMS-TQ RX series equipped with the Multi-Mode Injection Unit (MMI).<h4><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=GCMS-TQ8040+RX">GCMS-TQ8040 RX&nbsp;</a></h4>Delivering highly sensitive multi-component simultaneous analysis, the system improves operational efficiency through Analytical Intelligence , while also providing performance as a single GC-MS. The GCMS-TQ RX Series is a versatile triple quadrupole GC-MS that demonstrates high performance across a wide range of application fields. By combining it with the newly developed Multi-Mode Injection Unit (MMI), multiple injection methods are supported and analytical capability is further expanded.<h4>Multi-Mode Injection Unit (MMI)&nbsp;</h4>The Multi-Mode Injection Unit (MMI) supports a wide range of injection modes in a single unit, including split/splitless (SPL), programmable temperature vaporization (PTV), large-volume injection (LVI), direct injection, and thermal desorption/extraction (TD/TE). Dedicated software with an intuitive user interface enables easy method creation and seamless method transfer, simplifying analytical workflows. In this Application News, use of the MMI enables a threefold increase the injection volume compared with conventional injection methods, while maintaining peak shape.<h4>Conclusion&nbsp;</h4>Using the GCMS-TQ8040 RX and the MMI, volatile PFAS in textiles were analyzed. The results showed that all compounds measured in this study could be analyzed at 25 ppb or below. Furthermore, in the spike recovery test at the EU POPs regulatory limit of 25 ppb, recoveries were within 80 to 120 % for all compounds, showing good results. By increasing the injection volume with the MMI, trace levels of volatile PFAS can be measured even with the standard GCMS-TQ8040 RX model.<h3>3.

Waters Corporation: Extending PFAS Analytical Workflows with APGC-MS/MS Analysis: A Method for 35 GC-Amenable PFAS Compounds</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/720009500_en_4b615b3bc2.pdf">Full PDF for download</a></li></ul><h4>Benefits&nbsp;</h4><ul><li>An APGC-MS/MS method for the analysis of 35 GC-amenable PFAS allowing for characterization of PFAS samples beyond the suite of commonly targeted LC-MS/MS compounds, for a more complete assessment of PFAS burden</li><li>Injection of samples already extracted for LC-MS/MS analysis is possible without having to perform solvent exchange, saving time and labor &nbsp;</li><li>Sensitive and robust analysis to detect trace levels of PFAS in samples</li></ul>Routine PFAS analysis most commonly utilizes liquid chromatography (LC) as the separation technique and is the basis for most standardized methods that are currently available. While this is a key technique in the analysis of PFAS, there are classes of volatile and semi-volatile PFAS that do not chromatograph well using LC and require the use of gas chromatography (GC) to be successfully analyzed. Classes of PFAS that favor GC analysis include, but are not limited to, fluorotelomer alcohols (FTOH), fluorotelomer acrylates (FTAcr), fluorotelomer methacrylates (FTMAC), and fluorotelomer acetates (FTOAc). Additionally, there are classes that can be analyzed using both LC and GC techniques, including sulfonamides (PFSA) and sulfonamidoethanols (PFSE).&nbsp;All of these compounds are considered precursor compounds that terminally transform into the most widely studied PFAS, perfluoroalkyl carboxylates (PFCA) and perfluoroalkyl sulfonates (PFSA). Not only are they precursors in the synthesis of PFCA and PFSA end products, they are also intentionally used in products such as food packaging and textiles to impart grease and water proofing qualities.&nbsp;These precursor compounds are also discharged into the environment through similar routes as their end products (landfills, manufacturing waste, firefighting foams, etc), but also through volatilization, transport and deposition through the atmosphere either in the gas phase or bound to particulates. Like most PFAS, not much is known about the human toxicity of these particular PFAS, although some animal and in vitro studies do point to similar health effects as more commonly studied PFCAs and PFSAs, including liver and kidney toxicity, endocrine disruption and negative immune effects.1-4 Furthermore, their ability to transform in the environment to PFCAs and PFSAs, which are known to have toxic health implications, make them of concern.&nbsp;GC-MS/MS analysis for the volatile and semi-volatile GC amenable PFAS provides an additional tool in the workflow of PFAS sample analysis, increasing the comprehensiveness of sample characterization. In this application note, the development of an atmospheric pressure gas chromatography (APGC) coupled to tandem quadrupole mass spectrometry (MS/MS) method will be presented. Application of this method to authentic samples will be explored in a companion application note.<h4>Experimental</h4><ul><li>GC system: <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=8890">Agilent 8890&nbsp;</a></li><li>Autosampler: <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=7693A">7693A ALS</a></li><li>MS system: <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/554">Xevo™ TQ Absolute Mass Spectrometer&nbsp;</a></li><li>Ionization mode: API+</li></ul><h4>Conclusion&nbsp;</h4>An optimized APGC-MS/MS method for the analysis of 35 GC amenable PFAS has been presented, providing a practical way to extend existing workflows with sensitive and accurate analysis for fluorotelomer alcohols, acrylates, methacrylates, acetates, sulfonamides and sulfonamidoethanols. This approach could integrate seamlessly with existing LC-MS/MS workflows, allowing labs to extend compound coverage without requiring changes to established sample preparation protocols. Performance for all compounds was found to be optimal with the use of a siltek deactivated inlet liner and a 30 m x 0.25 mm ID, 0.50 µm Rtx-200 column. This configuration allows for the injection of samples pre-extracted for LC-MS/MS analysis that are in mainly methanol and water, allowing labs to generate additional insights without increasing sample prep burden. Method LLOQs ranged from 0.005 – 5.0 ng/mL, with most compounds being below 0.10 ng/mL, delivering robust performance across compound classes, indicating the method can be used for trace level applications. Overall, APGC-MS/MS adds a complementary capability to LC-MS/MS methods, allowing labs to comprehensively assess PFAS contamination for better understanding and informed regulatory or product safety decisions. Further application notes will demonstrate the use of this method in environmental and food packaging samples, highlighting how labs can gain more complete PFAS insights while leveraging existing workflows.</div></div></div></div></div></div></section>

Phenomenex: How to Achieve FAST GC METHODS without altering the Resolution

How to Achieve FAST GC METHODS without altering the Resolution

Have you ever had a question about your GC/GCMS analysis and thought, &quot;I have no idea what to do,&quot; or that because the question seemed so simple, everyone must already know the answer and &quot;I’m the only one who doesn’t know what to do.&quot; We can assure you that you are not alone.
If you have a question, we can guarantee that you are not the first... nor the last person to ask it. Sometimes the simplest of questions can have the most complex answers. A question about which liner to use can lead to a discussion on the benefits of glass wool versus glass frits. A question about how long a column should last may trigger a discussion about the importance of a leak free system, the maximum temperature limit, proper phase selection, and how an application may benefit from using backflush.
There’s no such thing as an easy answer, because the answer always depends on many different factors. Therefore, we have complied a list of some of our most frequently asked questions, which may seem like simple questions, but in reality they have anything but simple answers.
Why not submit your question to us in advance when you register for the webinar.
<h3>By attending this webinar you will learn:</h3>
<ul>
<li>best practices with GC and GC/MS systems – from liner and column selection to why gas filters matter and instrument prep recommendations, and</li>
<li>why there is not always an easy answer to most GC(MS) questions</li>

There a number of ways that the analysis time can be reduced. All depends on how well the components are separated in the present application.
<ul>
<li>Most easy is to trade in some resolution for speed using higher gas velocities or using a shorter column.</li>
<li>If the exact separation must be maintained, a choice has to be made between using hydrogen as carrier gas, or use a smaller ID capillary column (or a combination). </li>
<li>Important is that in the new method, the same chromatogram must be obtained. Using the EZGC method translator, you can simply calculate the oven program you need for that.</li>

Carrier gas is a necessary component to any functioning gas chromatographic system. The rising cost of helium, due to a global shortage in supply, has forced labs to consider alternatives such as hydrogen or even nitrogen, but is this a smart choice? Does it make sense for your laboratory? What are the common pitfalls or issues that might arise? In this talk we will take out some of the guess work associated with making this important decision and help you decide if the switch is right for you.

Agilent Technologies: Enhance Your Lab Productivity School Series: GCMS Chapter

Enhance Your Lab Productivity School Series: GCMS Chapter - Basic

We probably have all experienced this at some point when performing gas chromatography and our peak shape begins to appear a bit different.
Often the best way to approach troubleshooting is to also consider what ‘cannot’ cause an issue so that precious time is not spent addressing something that cannot cause the issue. This webinar will arm you with some simple tools, and a different way to look at troubleshooting, should a problem arise.
