209-200-180Growing concern over microplastics in human tissue calls for analytical methods with high sensitivity and strong polymer specificity. Conventional pyrolysis GC–MS is widely used, but limited separation can obscure complex mixtures and make closely related polymers difficult to distinguish. Pyrolysis GCxGC-TOFMS provides substantially improved chromatographic resolution for trace, non-targeted characterization,...Access Characterization of Microplastic Pyrolytic Markers...The Utility of Pyrolysis–Gas Chromatography–Time-of-Flight Mass Spectrometry for the Characterization of Polystyrene
203-821-732Pyrolysis–gas chromatography–time-of-flight mass spectrometry (Py-GC-TOFMS) is a powerful technique for characterizing polymers that are difficult to analyze directly due to their high molecular weight or limited volatility. By thermally decomposing the polymer into smaller, volatile fragments, Py-GC-TOFMS generates reproducible chromatographic “fingerprints” that enable identification, quality control, and detection of additives...Access The Utility of Pyrolysis–Gas Chromatography–Time-of-Flight...Determination of Moisture and Ash in Pet Food
203-821-724Determining moisture and ash in pet food is fundamental for quality control, regulatory compliance, and nutritional evaluation. Pet food nutrient guarantees (protein, fat, fiber, etc.) are expressed on an as-fed basis and moisture content affects how these nutrients are calculated. High moisture content often reflects a lower nutrient concentration. To...Access Determination of Moisture and Ash...

Statistical Differentiation of Tequila Spirits Using SPME-GCxGC-TOFMS and ChromaTOF Tile Software
Tequila is a Mexican distilled spirit produced from sugars derived from Agave tequilana Weber var. azul. Regulations allow a minimum of 51% agave sugars, while "100% agave" tequila must be made exclusively from agave. Its designation of origin restricts production to specific Mexican regions, including Jalisco, Nayarit, Tamaulipas, Michoacán, and...Access Statistical Differentiation of Tequila Spirits...Constant Split Ratio GC Flow Splitter for Splitting to FID and Mass Spectrometer
There are two common flow splitters in gas chromatography, unpurged and purged splitters. Unpurged splitters are simply a tee or "Y" fitting with the column flow split to two detectors. The purged splitter has the same three connections plus a connection for a makeup flow for pressure regulation at the...Access Constant Split Ratio GC Flow...Characterization of Engineered Polymers Using Thermal Desorption/Pyrolysis, Enhanced Chromatography, and High-Resolution Mass Spectrometry
