## THIN-LAYER CHROMATOGRAPHIC SCREENKG AND CONFIRMATION OF BASIC DRUGS OF ABUSE IN URINE Thin-layer chromatographic procedures are presented for the positive identification of methadone, primary metabolite of methadone (2-ethytidine-L15-di\_methyi-3,3\_dEpE,enytpyrra~d~~e), propoxyphene, oorprapox
The efficiencies of fifteen thin-layer silica gel chromatographic systems for separating commonly encountered neutral drugs are compared. The discriminating powers of the systems are measured both individually and in combination. Chloroform-acetone (4:1) is found to be the best system. The combinati
The efficiencies of fifteen thin-layer silica gel chromatographic systems in separating commonly encountered acidic drugs are compared. The discriminating powers of the systems are measured both individually and in combination. Ethyl acetate and chloroform-methanol (9:l) are found to be-the two best
