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.
采用高灵敏度气相色谱法研究了硫酸苯丙胺中的痕量杂质。这些杂质的浓度在不同批次之间差异很大，而批次内的差异通常很小。该方法用于将查获的硫酸苯丙胺追溯到共同来源，进而有助于追踪这种药物的非法分销链。
