导论目前,日益需要有一种灵敏的方法来定性和定量测定怀疑中毒病人血液中的药物及其代谢产物。关于这种测定已报导了各种不同的方法(薄层色谱法、紫外分光光度法、高效液相色谱法和气相色谱法)。使用两根柱子和两个氮磷检测器的气相色谱仪(GC)的灵敏度能对许多药物进行 Introduction At present, there is a growing need for a sensitive method for the qualitative and quantitative determination of drugs and their metabolites in the blood of patients suspected of being poisoned. A variety of different methods have been reported for this assay (thin layer chromatography, UV spectrophotometry, high performance liquid chromatography, and gas chromatography). The sensitivity of a gas chromatograph (GC) that uses two columns and two nitrogen and phosphorus detectors enables many drugs
