UPLC-MS/MS法同时测定尿液中的6种苯丙胺类毒品
Chinese Journal of Analysis Laboratory(2015)
Abstract
建立了固相萃取-起高效液相色谱-质谱法(SPE-UPLC-MS/MS)联用技术定量测定尿液中的6种苯丙胺类毒品.样品经Oasis HLB柱提取、纯化后,采用电喷雾离子源电离(ESI)、正离子多反应监测(MRM)模式质谱进行定性和定量分析.6种苯丙胺类毒品分别在0.1~10 ng/mL,0.2~20 ng/mL和0.5 ~ 50 ng/mL范围线性良好,相关系数不低于0.9993,提取回收率高于85%,RSD小于10.0%.方法可用于尿液中痕量苯丙胺类毒品的分析.
