Determinación de PFAS en aguas ambientales mediante DHS-GCxGC-TOFMS

This research demonstrates a solvent-free method for extracting volatile and semi-volatile PFAS from water using Dynamic Headspace (DHS) and Thermal Desorption. By utilizing GCxGC-TOFMS, the method provides the superior resolution and sensitivity required to identify over 15,000 PFAS variants in complex matrices.
