✦ Synopsis

Trace impurities in amphetamine sulphate were studied by a highly sensitive gas chromatographic method. The concentration of these impurities varied considerably between batches whereas the variations within the batches were usually very small. The method is used for the assignment of seizures of amphetamine sulphate to common sources, which in turn may permit chains of illicit distribution of this drug to be traced.

Chemical signatures (or impurity profiles) of methamphetamine hydrochloride were displayed by gas chromatography. The analyses of samples from two series of batches showed that the inter-batch variation of signatures was significantly greater than the corresponding intra-batch variation. In many cas
