中文摘要：

吸毒后驾驶（简称＂毒驾＂）案件中,科学证据的检验方法对相关法律法规的制订以及案件公平公正的处理具有重要意义。本研究以微量陈旧血样中安非他明类毒品为分析目标,建立了一种气相色谱-正离子化学电离-串联质谱（GC/PCI-MS/MS）检测方法,并将其应用于370份交通事故案件中＂酒驾＂检测后剩余的微量陈旧血样。结果表明,该方法的灵敏度高、回收率好,测试样品中安非他明类毒品的检出率约为0.27%。上述研究结果不仅为我国＂毒驾＂案件的处理提供了一种高效的检测方法,而且为相关法律措施的制订提供了重要的参考数据和研究思路。

英文摘要：

Scientific evidence in drug-driving cases and its analysis methods play an important roles in traffic-related legislation and legal justice. The method of gas chroma- tography-positive chemical ionization-tandem mass spectrometer （GC-PCI-MS/MS） was utilized in sample preparation and analysis process, in order to detect the amphetamines in trace and decayed blood samples. 370 blood sample residues were collected from traffic accident cases and tested for blood re-tested for amphetamines. The results detection （LODs） for four amphetamines, alcohol concentration （BAC）, which w indicate that the method has low limits show a recoveries. Approximately 0.27 % of the blood sampl mines. The results provide an efficient method for d ere good linearity and high extraction e residues are positive for amphetarug-driving cases as well as important data for the related legislation.
