QuEChERS结合超高效液相色谱-串联质谱法同时测定畜禽肉中9种新烟碱类杀虫剂及5种代谢物残留量OA北大核心CSTPCD
Simultaneous Determination of Nine Neonicotinoid Insecticides and Five Metabolites in Meat by QuEChERS Coupled with Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry
本研究使用QuEChERS(Quick、Easy、Cheap、Effective、Rugged、Safe)净化结合超高效液相色谱-串联质谱法建立同时测定畜禽肉中新烟碱类杀虫剂及其代谢物残留量的方法.样品经1%乙酸-乙腈提取,加入盐析剂(1 g NaCl、4 g无水MgSO4)盐析分层,上清液用C18粉末净化后经XSelect HSS T3(150 mm×3.0 mm,2.5 μm)色谱柱进行分离,以0.1%甲酸溶液和乙腈为流动相梯度洗脱,在正离子…查看全部>>
In this study,a method for the simultaneous determination of neonicotinoid insecticides and their metabolites in meat was established by the QuEChERS(quick,easy,cheap,effective,rugged,safe)pretreatment method followed by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).Samples were extracted with acetonitrile containing 1%acetic acid.After salting-out with 1 g of NaCl and 4 g of anhydrous MgSO4,the supernatant was cleaned-up …查看全部>>
