A method for identifying lysergic acid diethylamide (LSD) in seized microgram quantities produces small pure crystals suitable for analysis with a microscope sampling device and Fourier transform infrared (FT/IR) spectrometer. The technique yields excellent spectra from samples containing less than 50 µg of LSD and can distinguish LSD from iso-LSD and lysergic acid N-methylpropylamide (LAMPA). The approach combines preparative thin-layer chromatography with wick evaporation, an older technique for separating soluble components from high-solid mixtures without filtration.
