Continued illicit use of the potent psychedelic drug lysergic acid diethylamide (LSD) has stimulated efforts to develop effective analytical methods for detection of the drug and its metabolites in body fluids from suspected LSD users. Recently reported methods based on gas and liquid chromatography, combined with single- and multiple-stage mass spectral analysis, now permit accurate detection...
Procedures for detection and quantitation of lysergic acid diethylamide (LSD), iso-LSD, and N-demethyl-LSD by capillary chromatography/tandem mass spectrometry (GC/MS/MS) are presented. Several methods for derivatization, sample introduction, and ionization, in combination with mass spectrometry/mass spectrometry (MS/MS), have been evaluated for overall ionization efficiency and product-ion...
