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.
LCGC North America
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.
The Column
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.
