Measurement of PFAS in indoor air and investigation of source materials
Application Note 167
This study investigates the performance of Markes’ TD100-xr™ high through-put automated thermal desorption (TD) instrument coupled to a gas chromatograph (GC) and a triple quadrupole mass spectrometer (MS/MS) for PFAS analysis.
This instrument combination enables measurement of per- and polyfluoroalkyl substances (PFAS) in indoor air at a detection limit as low as 1 pg for Me-FOSA. When using sampling chambers to test materials, the PFAS they release into the indoor air can be identified, along with quantifying the emission rate of such releases.
