Abstract

The Ion Trap Detector (ITD), a relatively new gas chromatographic detector from Finnigan MAT, was evaluated for its suitability in confirming urine specimens found positive for cannabinoids by immunoassay techniques. Also presented is a procedure for the isolation of 11-nor-delta 9-THC-9-carboxylic acid (THC-COOH) from human urine by bonded-phase absorption chromatography.
