Chromatographic behavior of performance-enhancing drugs on thin layers of bismuth silicate ion exchanger

The chromatographic behavior of amphetamine, bemegride, caffeine, chlorphentermine, ephedrine, ethylamphetamine, isoproterenol, methadone, methylendioxyamphetamine, pentazocine, pethidine, pemoline, strychnine, and salbutamol has been studied on thin layers of bismuth silicate anion exchanger with organic, aqueous, and mixed organic-aqueous mobile phases. Rapid separations of one drug from many other drugs and also many quaternary, ternary, and binary separations have been achieved and are discussed. A new variable, SRF has been introduced to quantify the separating power of the bismuth silicate anion exchanger in thin-layer chromatography.
