A procedure for the determination of LSD (lysergic acid diethylamide) in urine at concentrations as low as 0.5 ng/ml is presented. After addition of deuterium-labeled LSD as the internal standard, a rapid n-butyl chloride extraction of LSD from urine at pH 8 is followed by formation of the trimethylsilyl (TMS) derivative by treatment with N,O-bis(trimethylsilyl)trifluoroacetamide. The TMS...
