A classification system is described for drugs using thin-layer chromatography (TLC), gas-liquid chromatography (GLC) and ultraviolet (UV) spectrophotometry. The TLC classifications are based on division of the plate into zones relative to a set of mixed drug standards. The GLC classification is based on Kovats' retention indices. The procedure for classifying drugs is presented, together with a list of over 200 classified drugs.
