目的建立血液和胃液中啶虫脒的快速定性测定方法。方法血液和胃液中的啶虫脒经二氯甲烷萃取,冷氮吹干后,残留物用二氯甲烷溶解,再用气质联用仪进行定性分析。结果血液和胃液中的啶虫脒可以在90 min内完成检测,得到的总离子流图显示啶虫脒能与血液中杂质很好地分离;样品质谱图与标准质谱图的匹配度达99%,可得到准确可靠的定性分析结果。结论该方法能快速准确地定性分析血液和胃液中的啶虫脒成分,值得推广。
Objective To establish a rapid and qualitative method for the determination of acetamiprid in blood and gastric juice. Methods Acetamiparine in blood and gastric juice was extracted with dichloromethane. After cold nitrogen was dried, the residue was dissolved in dichloromethane and qualitatively analyzed by GC / MS. Results Acetamiprid in blood and gastric juice could be detected within 90 min. The total ion chromatogram showed that acetamiprid was well separated from the impurities in blood. The match of the sample mass spectrum with the standard mass spectrum was 99% , You can get accurate and reliable qualitative analysis results. Conclusion The method can qualitatively and rapidly analyze the acetamiprid in blood and gastric juice, which is worth to be popularized.
