Scientists recently used thermal desorption (TD) and gas chromatography– time-of-flight mass spectrometry (GC×GC-TOFMS) to track per- and polyfluoroalkyl substances (PFAS) emissions from materials used in firefighter gear.

Jonathan Zweigle of the University Tübingen spoke with LCGC International about his work using non-targeted screening based on high-resolution mass spectrometry (HRMS) to detect PFAS in soil samples. HRMS allows scientists to determine the elemental and isotopic composition of a sample with high accuracy.
