A rapid and simple procedure is described for the mass screening and confirmation of amphetamine and methamphetamine in urine using gas chromatography with flame ionization detector. The amphetamine drugs are screened as free drugs on a 10% Apiezon L-10% KOH column and confirmed as their trifluoroacetamide derivatives on a 3% OV-17 column. This dual approach eliminates false positives and interfering substances that may be present in the urine and is, therefore, specific for amphetamine and methamphetamine.
描述了一种快速简便的程序，用于使用带有火焰离子化检测器的气相色谱法对尿液中的苯丙胺和甲基苯丙胺进行大规模筛查和确认。苯丙胺类药物在10%阿皮松L - 10%氢氧化钾柱上作为游离药物进行筛查，并在3% OV - 17柱上作为其三氟乙酰胺衍生物进行确认。这种双重方法消除了尿液中可能存在的假阳性和干扰物质，因此对苯丙胺和甲基苯丙胺具有特异性。
