Quantitative Analysis of PFAS in Drinking Water Using Liquid Chromatography Tandem Mass SpectrometryPer- and polyfluoroalkyl substances (PFAS) are found in firefighting foams and consumer products. They are ubiquitous in the environment and are an emerging human health concern. This work compares the 2009 and 2018 revised US Environmental Protection Agency (EPA) LC–MS/MS methods of analysis for PFAS in drinking water.

Gas Chromatography–Mass Spectrometry Characterization of Vegetable Oil–Derived Potent Antimicrobial AgentsUnder a suitable thermal oxidation regime, vegetable oils yield a mixture of volatile and semivolatile organics that exhibit very high antimicrobial activities against a variety of microbial species. Volatile and semivolatile products were characterized with GC–MS using electron ionization and chemical ionization. The thermal oxidation of vegetable oils resulted in the formation of an array of shortand medium-chain acids, aldehydes, and ketones that act synergistically to yield a potent antimicrobial disinfectant.

Mass Spectrometry Techniques to Unravel the Heterogeneity of GlycoproteinsSince glycans are responsible for bioactivity, solubility, immunogenicity, and clearance rate from circulation, it is vital to have a detailed map of glycans in therapeutic glycoproteins. Detailed glycoprotein structural analysis must be able to identify the peptide sequence where the glycans are attached as well as the structure of the glycan portion, including oligosaccharide sequence and glycosyl linkages. This article details methods for mass spectrometry experiments on both released glycans (“glycomics”), as well as on intact glycopeptides (“glycoproteomics”) using electron transfer dissociation, high-energy collision dissociation, and collisioninduced dissociation fragmentation pathways, which are needed to fully elucidate the structure of glycoproteins.
