Characterization of PFAS and Other Pollutants in Household Dust Using GCxGC-HRTOFMS and Spectral Analysis Tools (SAT)
203-821-713The goal of this work was to develop a methodology for the untargeted analysis of a dust standard reference material (NIST 2585) as well as dust samples collected from household and office settings for both legacy and emerging pollutants. The method uses two-dimensional gas chromatography (GCxGC) and high-resolution mass spectrometry...Access Characterization of PFAS and Other...Chemical Profiling of Commercially Available Cola Beverages Using GC-TOFMS and ChromaTOF Sync
203-821-712In this study, HS-SPME was used to extract the Volatile Organic Compounds (VOCs) of 13 commercially available cola beverages for analysis by GC-TOFMS. The data were then processed using our data alignment tool ChromaTOF Sync, which compiles peak information through sets of samples by performing automated peak finding and deconvolution...Access Chemical Profiling of Commercially Available...Sensory-Directed Analysis for Beer Aroma Profiling: Stacking Multiple SPME Extractions to Help Connect Olfactory and GC-MS Data
203-821-711This application note highlights how stacking multiple SPME extractions with GC-MS and GC-Olfactory can improve detection of low-level analytes in complex samples, such as beer, allowing researchers to identify compounds that might otherwise go unnoticed. It demonstrates the value of sensitive techniques for revealing impactful analytes that contribute to aroma...Access Sensory-Directed Analysis for Beer Aroma Profiling...Packaging Contaminants in the Headspace of Commercially Available Cola Beverages
203-821-710This application note explores the analysis of packaging-derived contaminants in the headspace of commercially available cola beverages using GC×GC-TOFMS with ChromaTOF Sync. The study focuses on identifying volatile organic compounds (VOCs) that may migrate from packaging materials into the beverage, potentially affecting quality, safety, and regulatory compliance. Using comprehensive two-dimensional...Access Packaging Contaminants in the Headspace...Determination of Carbon Black in Polypropylene
203-821-709National and regional regulations provide guidance on the approved grade and type of Carbon Black, and some regulations specifically restrict the amount of Carbon Black that may be present in plastics designated for food contact. A common method for determining the content of Carbon Black in polymer materials is thermogravimetric...Access Determination of Carbon Black in...
