Extraction of 11-nor-9-carboxy-Δ9-tetrahydrocannanbinol from Urine Using ISOLUTE® SLE+

This application note describes the extraction of THC and metabolites from urine using ISOLUTE SLE+ columns or plates. It shows how ISOLUTE SLE+ Supported Liquid Extraction plates and columns offer an alternative to traditional liquid liquid extraction (LLE) for bioanalytical sample preparation, providing high analyte recoveries, no emulsion formation and reduced sample preparation time.
