Abstract
The Ion Trap Detector™ (ITD), a relatively new gas chromatographic detector from Finnlgan 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-Δ9-THC-9-carboxyllc acid (THC-COOH) from human urine by bonded-phase absorption chromatography.This publication has 4 references indexed in Scilit:
