QuEChERS-超高效液相色谱-串联质谱法测定坚果中38种农药残留OA北大核心CSCDCSTPCD
Determination of 38 Kinds of Pesticide Residues in Nuts by QuEChERS-Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry
建立了检测4种坚果(花生、杏仁、腰果、核桃)中38种农药残留的QuEChERS-超高效液相色谱-串联质谱(UPLC-MS/MS)方法.样品均质后,用乙腈进行提取,经PSA和C18净化后,采用Oasis PRiME HLB固相萃取柱进一步净化, UPLC-MS/MS分析.对样品前处理和色谱方法进行了优化.在多重反应监测(MRM)模式下进行质谱分析,外标法定量.38种农药的检出限范围(S/N=3)为0.01~10 μg/kg,定量限(S/N=10)为…查看全部>>
A multi-residue analysis method was developed for the determination of 38 kinds of pesticides in nuts (almonds, peanuts, cashew nuts and walnuts) by QuEChERS-ultra-high performance liquid chromatography-tandem mass spectrometry.The pesticide residues were extracted with acetonitrile.The extract was cleaned up with PSA, C18 and Oasis PRiME HLB, and then analyzed by UPLC-MS/MS with multiple reaction monitoring (MRM) mode.External standard method was employed t…查看全部>>
