建立了一种同时检测植物性食品中多种不同种类农药残留的方法,采用乙腈提取,SPE净化,UPLC-MS/MS分析,在4种不同基质中添加的3个浓度的回收率在70.3%~108.5%之间,相对标准偏差(n=6)均小于7%。
A method was developed for simultaneous detection of various pesticide residues in plant foods. The recoveries of the three concentrations in four different matrices were extracted by acetonitrile, SPE and analyzed by UPLC-MS / MS. The recoveries of the three concentrations were 70.3% ~ 108.5%, the relative standard deviations (n = 6) were less than 7%.
