Comparison of dual sorbent solid phase extraction for PFAS applications

Many laboratories have opted to combine polymeric weak anion exchange (WAX) and graphitized carbon black (GCB) into single solid phase extraction (SPE) cartridges to streamline sample preparation and facilitate automation for the determination of Per- and Polyfluoroalkyl Substances (PFAS) in environmental samples. The Agilent PFAS WAX and Carbon S sorbents are specifically manufactured for PFAS applications and are lot-tested to ensure low PFAS residue and maximum recovery.

The extraction performance of the dual-phase Agilent Bond Elut PFAS WAX/Carbon S SPE cartridges are comparable to other commercial cartridges, ensuring seamless integration into existing workflows while assuring optimal performance for PFAS applications.
