A simple and sensitive identification system for the detection of a broad spectrum of drugs is described. ChemElut extraction tubes were used for isolation of drugs from urine. Specimens were screened by thin-layer chromatography (TLC) and confirmed by gas chromatography/mass spectrometry (GC/MS). Special procedures for buprenorphine, cannabinoids, cocaine, LSD, morphine, phencyclidine, halogenated hydrocarbons, paracetamol, and alcohols were used. This system is useful for screening samples in… CONTINUE READING
