Determination of OCPs and PCBs in Sediments Using SPE-GCxGC-TOFMS

This application note describes an analytical workflow that utilizes solid-phase extraction (SPE) for the cleanup and enrichment of sediment samples prior to analysis by GCxGC-TOFMS using the LECO Pegasus BTX 4D system. The protocol focuses on the simultaneous determination of multiple target OCPs and PCBs, addressing the analytical requirements associated with complex environmental matrices and regulatory criteria.
