Measurement of PFAS in indoor air and investigation of source materials

In this application note, Markes investigates the performance of its TD100-xr™ high-throughput automated thermal desorption (TD) instrument. The instrument is coupled to a gas chromatograph (GC) and a triple quadrupole mass spectrometer (MS/MS) for PFAS analysis.
