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>

They have musty/earthy odors and very low odor thresholds, meaning they can be smelled at concentrations of 1-10 ppt in water. As a result, products, such as whiskey, that use contaminated water in the process may have musty, earthy odors in the finished product. Due to the complexity of the whiskey matrix and the low odor threshold of MIB and geosmin, they can be challenging to quantify accurately. This work shows that a selectable, heartcutting 1D/2D-GC-MSD is required to accurately quantify MIB and geosmin in finished whiskey. &nbsp;<h5>Key Learning Objectives/What attendees will learn:</h5>1.

This can be negatively perceived by consumers and often leads to an aftertaste of these characteristics lingering in the mouth after the wine has been swallowed. Wildfires plagued the counties in northern California and Oregon during the 2020 wildfire season from August through October. These fires severely impacted the grape harvest and challenged wine makers as many of their vineyards were either destroyed or their crops were contaminated with smoke taint. Numerous wineries opted to release limited amounts of 2020 Pinot Noir for this reason or produce rosé or white wines from affected grapes. Our research will look specifically at three different vintages (2019, 2020 and 2021) of Pinot Noir from the same vineyard in the Willamette Valley region of Oregon. It should be noted that “smoke” as an indicator of taste in wines is not always an indicator of smoke taint but can also be imparted into the wine by aging in oak barrels.We will compare headspace based GCMS techniques to characterize these wines and profile the volatile phenol content. Solid phase micro extraction (SPME) and stir bar sorptive extraction (SBSE) will be used to analyze both free volatile content and gylcosidically bound phenolic content. The free volatiles will be acquired in unaltered wine to best represent the consumer’s initial experience. These samples will then experience a pH adjustment, sonication and heat treatment to release gylcosidically bound phenolic compounds which could potentially be released over time by aging the wine.Our research will characterize the phenolic compounds contributing to the smoke taint odor and flavor present in the Pinot Noirs against the sugar bound compounds that can potentially release over the shelf life of the wine utilizing SPME and SBSE extraction methods. Additionally, the comparison of vintages will indicate whether the phenolic characteristics obtained by GCMS can be used to capture the smoke defect in the wine profile from 2020.<h5>Key Learning Objectives/What attendees will learn:</h5>1. Theory and applicability of SHS, SPME, SBSE, TF-SPME, DHS, and pyrolysis.2. How to decide on the most optimal extraction technique based on research challenges.<h4>Presentation 2: An Exploration of Phenolics in Red Wines: Chemical and Sensory Effects of Selected Winemaking Techniques</h4><ul><li>Dr. L. Federico Casassa, Associate Professor, Enology, Cal Poly</li></ul>This presentation discusses how the winemaker can manage winemaking elements – those over which we have control – to develop, evolve and enhance mouthfeel, with focus on phenolic compounds in grapes and wines from the Central Coast of California. The discussion then covers which elements can be leveraged and managed during the production of the wine. There are known protocols for grapes, yeast, fermentation, and aging. However, the challenge for the winemaker is to understand how our various treatments affect the end product. This presentation covers the effects of fermentation temperatures, cold soaking and how the manipulations of these elements can be used to modulate astringency and mouthfeel in the wines.<blockquote>Presenter: Stephen Toth (GCMS specialist in the Structure Elucidation Department, International Flavors &amp; Fragrances (IFF))Stephen Toth is a GCMS specialist in the Structure Elucidation Department at International Flavors &amp; Fragrances (IFF) in Union Beach, NJ.
