Analysis of PFAS in Locally Acquired Food Containers

The combination of an untargeted approach using ultrahigh pressure liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC–QTOF) and a targeted approach using UHPLC–tandem mass spectrometry (MS/MS) are presented as an ideal method for detecting per- and polyfluroalkyl substances (PFAS) in fast-food packaging.

Quantification of Polybrominated Diphenyl Ethers in Avian Dried Blood Spots by Gas Chromatography–Tandem Mass Spectrometry Coupled with Simple Sample Preparation

With a simple liquid extraction approach and a short, 13-min GC method, dried blood spots can be analyzed effectively and rapidly. This method demonstrates that dried blood spot cards are an effective technique for toxicological studies.

A Miniature Static Headspace–GC Method for the Analysis of Methanol in Biodiesel

An autosampler for a standard gas chromatography (GC) or GC–mass spectrometry (MS) system was adapted to perform simple static headspace sampling, instead of using a separate, and potentially more complicated, headspace sampling unit.
