对人血液中鸦片类、苯丙胺类、可卡因类等26种毒品的提取方法、净化方法、色谱条件及质谱条件进行了研究,建立了液相色谱-串联质谱法检测人血液中26种常见毒品的检测方法。方法检测限为1～2μg/kg。在2～200μg/kg范围内,相关系数为0.9771～0.9995。在5～50μg/kg范围内,26种常见毒品的回收率在63%～104%之间,相对标准偏差为1.3%～14%。方法能够满足日常快速检测工作要求。
The extraction methods, purification methods, chromatographic conditions and mass spectrometry conditions of 26 kinds of drugs such as opiates, amphetamines and cocaine in human blood were studied. The determination of 26 kinds of common drugs in human blood by liquid chromatography-tandem mass spectrometry Detection method. The detection limit was 1 ~ 2μg / kg. In the range of 2 ~ 200μg / kg, the correlation coefficient was 0.9771 ~ 0.9995. In the range of 5 ~ 50μg / kg, the recoveries of 26 common drugs ranged from 63% to 104% with relative standard deviations of 1.3% to 14%. Methods to meet the daily rapid test requirements.
