title: More economical use of high-performance thin-layer plates for chromatographic screening of illicit drug samples.
abstract: A rapid thin-layer chromatographic method for the separation of illicit drugs and similar compounds by two simultaneous but different developments on the same chromatographic plate is described. One half of the plate was impregnated with an aqueous solution of KHSO4 and the whole plate developed in a Camag linear developing chamber from two opposite sides using methanol with 0.01 M KBr as eluent.
