Extraction of THC Metabolites in Urine using the Empore™ Membrane C18 Extraction Cartridge

Abstract

In this application note, the Empore membrane solid phase extraction cartridge is used to extract THC metabolites from urine samples as part of a routine sample preparation procedure. Specifically, the THC-OOH metabolite was quantified as part of this method.
