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>

Food and animal feed analysis typically relies on complex, slow and expensive techniques which can take hours or days to highlight problems with incoming and outgoing food ingredients, animal feeds and retail produce. The adoption of a rapid, inexpensive but accurate and reliable mass spectrometry based real time monitoring technology has the potential to provide a step-change in monitoring the safety and quality of food and feed.
This talk will demonstrate recent work undertaking using SICRIT technology for both targeted and untargeted food and feed monitoring tasks. Firstly, the capabilities of the SICRIT source when combined with a compact and inexpensive triple quadrupole mass spectrometer for targeted analysis will be discussed, followed by the use of the SICRIT source on both triple quadrupole and time-of-flight instrumentation for untargeted screening.
The potential for the implementation of one or more workflows within a factory or production environment, including the challenges and opportunities will then be introduced.
