Microplastics have emerged as one of the most widely discussed environmental contaminants of our time. Regardless of where we live, daily exposure to microplastics has become virtually unavoidable—these tiny plastic particles are present in the air we breathe, the water we drink, and the environments we inhabit. As researchers work to better understand the sources, transport pathways, and impacts of microplastics, the demand for reliable microplastic analysis methods continues to grow.While techniques such as FTIR and Raman spectroscopy have become standard tools for identifying microplastics, their utility is limited for smaller particles (i.e. nanoplastics) and in complex matrices. More advanced microplastic analysis methods can provide a deeper understanding of what these particles contain and how they may change over time in the environment.<div><h3>The Limits of Spectroscopic Microplastic Analysis Methods</h3>Fourier-Transform Infrared (FTIR) and Raman spectroscopy are widely used microplastic analysis methods because they can identify polymer types by measuring how electromagnetic radiation interacts with a material. These techniques are valuable for determining whether a particle is polyethylene, polypropylene, polystyrene, or another common plastic. For many studies, this information is sufficient to confirm the presence of microplastics, especially in clean samples with sufficient microplastic density.However, <a target="_blank" rel="noopener noreferrer" href="https://www.leco.com/application/environmental/">environmental samples</a> are rarely clean and compositionally simple. Microplastic particles can become weathered and obscured by other materials in the environment, making their accurate identification with spectroscopy difficult. Additionally, if researchers want to understand what additives, degradation products, or pollutants are associated with the plastic, particle identification alone is not enough. Thus, FTIR and Raman spectroscopy methods alone struggle to thoroughly characterize these complex chemical components, particularly in challenging environmental matrices. As questions surrounding microplastic exposure become increasingly important, researchers require analytical techniques capable of examining the chemistry of a sample in greater detail, not simply confirming the presence of the physical particle itself.</div><div><h3>Thermal Desorption and Pyrolysis GCxGC-TOFMS For Deeper Microplastic Analysis</h3>Thermal Desorption (TD) and Pyrolysis (Py) coupled with comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry (<a target="_blank" rel="noopener noreferrer" href="https://www.leco.com/core-analysis/gc-and-gc-ms/">GCxGC-TOFMS</a>) offer a powerful alternative for investigating nano- and microplastics in complex samples. These techniques provide complementary information about sample composition.&nbsp;Thermal desorption releases volatile and adsorbed compounds, including environmental contaminants, degradation products, and VOCs associated with microplastic particles. This can reveal important information about chemicals present within or on the plastic.Pyrolysis thermally deconstructs the polymeric material, breaking it into GC-amenable characteristic degradation compounds. These compounds act as chemical markers that can be used to identify the various polymers present. When analyzing complex or heavily weathered microplastics that may be difficult to characterize using traditional spectroscopic techniques, pyrolysis is particularly advantageous.The most significant benefit comes from pairing these techniques with comprehensive two-dimensional gas chromatography. Environmental samples often contain hundreds or even thousands of compounds that coelute in 1D GC-MS, making it difficult or impossible to identify each compound. GCxGC provides significantly greater separation capability, helping analysts distinguish important polymer markers from background matrix components. This enhanced separation improves the mass spectrometer’s ability to identify characteristic polymer pyrolysis products, even in highly complex environmental samples. As a result, researchers can detect and identify challenging microplastics without the extensive purification steps often required by other analytical workflows.Another unique advantage of this approach is that thermal desorption and pyrolysis can be used in series on the same sample. Together, they create a more complete chemical profile of the sample.</div><div><h3>A Powerful Microplastics Analysis Workflow for Deeper Insight into the Effects on Our Environment</h3>FTIR and Raman spectroscopy remain valuable tools for rapid screening and flagging samples containing microplastic particles. However, by combining thermal desorption, pyrolysis, and GCxGC-TOFMS, analysts can obtain a much more comprehensive view of plastics in their samples and their environmental implications. As environmental research continues to advance and concerns surrounding microplastic contamination grow, researchers will increasingly require information that extends beyond answering the question,&nbsp;“What plastic is present?”&nbsp;&nbsp;Ultimately, this deeper level of characterization can provide new insights into the environmental fate of microplastics and help scientists better understand their potential impacts on ecosystems and human exposure.</div>

Technology for Aroma, Flavour and Fragrance Analysis

As our understanding of the human impact on the environment deepens, so too does the conversation and action surrounding two linked topics: how companies can adopt more sustainable operations and which other compounds necessitate monitoring to address the latest safety and environmental concerns.
When trying to assess sustainability in a GC-based lab, organic solvents, liquid cryogen and helium are often at the top of lab managers&#39; lists to reduce. Hydrogen carrier gas, solvent-free, and cryogen-free sample introduction methods offer a solution to these problems. However, are they compatible with the expanding number of species and lower detection limits now required for many organic compound monitoring lists?
In this webinar, Hannah Calder, Environmental Air – Market Development Manager at Markes International, and Dr. Aaron Davies, Commercial Marketing Manager – Thermal Desorption at Markes International, will discuss case studies where air monitoring lists are growing in complexity, such as in ozone precursor monitoring, air toxics, and organic ozone-depleting substances. In each case study, as well as looking at how the methodology can meet the requirements of monitoring, they will also discuss how the method can be made more sustainable, ensuring longevity and accountability.
By attending this webinar, you will learn:
<ul>
<li>About proposed changes to monitoring of ozone precursors in Europe, air toxics in the USA and ozone depleting substances in China
</li>
<li>How sustainability can be introduced into laboratories analysing organic compounds, with a focus on air monitoring
</li>
<li>What the challenges are when adopting a more sustainable approach, and tools available to help facilitate the conversion process
</li>
</ul>
Who should attend?

<li>Researchers interested in monitoring of organic compounds
</li>
<li>Laboratory and project managers specialising in air samples
</li>
<li>Environmental consultants

Case studies where air monitoring lists are growing in complexity, such as in ozone precursor monitoring, air toxics, and organic ozone-depleting substances.

VOC monitoring requirements for air analysis

Learn how GC-based techniques widely used in VOC monitoring can be easily applied to PFAS analysis.
Exposure to per- and polyfluoroalkyl substances (PFAS) can occur through a number of pathways. One of the less understood, but equally important, routes is air. The movement of PFAS through air can happen relatively unimpeded when compared to water and soil, and deposition from the air is another way that they can become contaminated.
Sources of PFAS in the air can be industrial activity, disposal of PFAS containing materials or simply emissions from PFAS containing products. Monitoring of these different environments and matrices is commonly carried out using GC based techniques for other VOCs, so how does monitoring of PFAS differ? Join this webinar to hear about how techniques already broadly used for VOC monitoring can be successfully applied to PFAS measurements from air and materials.
By attending this webinar, you will learn:
<ul>
<li>Which PFAS are GC amenable and which make most sense to monitor with other techniques
</li>
<li>How current VOC monitoring standards can be applied to PFAS monitoring in air
</li>
<li>What changes to those methods mean in terms of performance and new challenges they introduce
</li>
<li>What detection limits are possible in air and what is needed for different environments and matrices
