Combining elemental analysis and molecular techniques to characterize Ancient Egyptian mummification balms

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>

According to the PIC/S guidance complex or open-ended processes that lead to subjective interpretation, can result in an increase in data failures. One way to reduce this risk is with a simplified, well-defined process. Empower software enables you with tools to create structure in your chromatographic processes and workflow. Leveraging a well-defined workflow along with a clear SOP that details important steps, such as how to work thru reprocessing of data, will reduce the risk of failures. More complexity added to a workflow can result in an increase in data review requirements and subsequently the associated audit trails.
In this workshop we will define a chromatographic workflow with Empower software to support data integrity goals. Starting with method development, method validation, and routine usage to data acquisition, data processing, reporting results, and using control charts to track and trend data.

Monitoring the quality of hydraulic and/or lube oils is critical to prevent premature wear of any kind of machinery. In this session we will look at this topic from a new perspective focusing on the combination of titration (potentiometric, thermometric, coulometric Karl Fischer titration) and Vis-Near-Infrared Spectroscopy (Vis-NIRS).
Combining titration (highly sensitive, specific, a widely used primary method) with Vis-NIRS (fast, non-destructive, results for multiple parameters at once) can make your oil condition monitoring and/or lubricant analysis much more efficient, especially, if your laboratory has to analyze large sample series every day.
Attending this session, you will learn and understand:
<ul>
<li>The specific advantages of each method (titration and Vis-NIR-Spectroscopy)</li>
<li>How and when to use these methods to measure critical chemical and physical parameters in lube and hydraulic oils</li>
<li>What thermometric titration is and how it helps to improve robustness of serial acid number testing</li>
<li>How to automate measurements of large sample series to increase efficiency and reproducibility</li>
<li>How Vis-NIRS for lubricant analysis complies with ASTM guidelines and can save costs and time</li>

Microplastics pollution in watersheds was reported as early as the 1970’s. Now microplastics are one of the prevalent constituents of marine pollution. Microplastics are differentiated from other plastic particles, being in the size regime of &lt;5 mm. These small plastics present a potential threat to marine ecosystems due to ingestion of the microplastics but have also been noted as a means of concentrating toxic pollutants that may then enter humans through consumption of marine animals. The first step to understanding the nature of a microplastics pollution problem is the correct identification of the plastics. Fourier transform infrared (FT-IR) spectroscopy is a primary analytical method for the identification of organic materials. FT-IR microspectroscopy is well-suited to analyze particles &lt; 5 mm in dimension through the combination of the focusing power of a microscope with the chemical identification capabilities of FT-IR spectroscopy.
We present the FT-IR microspectroscopic analyses of microplastics collected from water samples and living oceanic organisms as a means of tracing the microplastic contamination back to the originating source.
