ABSTRACT
Organochlorine Pesticides (OCPs) are a class of persistent contaminants that span the spectrum of EPA methodology. Typically analyzed by GC/ECD, florisil clean-up is often required prior to analysis to eliminate non-target interferences. The use of an automated SPE apparatus can enable the pairing of both extraction of aqueous samples with extract clean-up in a continuous process with no manual manipulation. A detailed examination of the procedure will be covered along with the fluidic pathways to accommodate the pairing of the extraction and clean-up steps. IPR, MDL and a variety of matrix specific validations were conducted testing the process. Final validation involved with participation in a commercial PT study by an accredited laboratory.
