Application Note: Untargeted screening of volatile per- and polyfluoroalkyl substances (PFAS) released during the application of aqueous film-forming foam (AFFF)
16 August 2022

In this application note, Markes demonstrates how thermal desorption with gas chromatography-mass spectrometry (TD–GC–MS) can be used to monitor the release of per- and polyfluoroalkyl substances (PFAS) during the application of aqueous filmforming foam (AFFF). The results of the study show that TD–GC–MS can be used to analyze target compounds and screen for non-target compounds, enabling researchers to gain a greater understanding of AFFF emissions.
