Analysis of trace per- and polyfluorinated organic vapours in air using cryogen-free thermal desorption and gas chromatography–mass spectrometry

In this application note, Markes describes the sampling and analysis of a challenging range of trace-level volatile and semi-volatile vapors of per- and polyfluorinated alkyl substances (PFAS) in air, using GC–MS technology and the TD100-xr™ automated thermal desorption (TD) system.
