Validation of QuEChERS Method Coupled with Liquid Chromatography-Mass Spectrometry to Determine 19 Pesticide Residues in Lettuce

摘要

QuEChERS method was known as the quick,easy,cheap,effective,rugged and safe method for multi pesticide residue analysis in foods,recently. In this article,QuEChERS method was validated to analyze 19 pesticide residues (propoxur, dimethoate, pyrimethanil, metalaxyl, isocarbophos, prometryn,fenarimol, ethoprophos, metolachlor, quinalphos, pirimifos-methyl, buprofezin, fluazifop-p-butyl,diclofop-methyl, chlorpyrifos, fenpyroximate, fenvalerate, propargite, bifenthrin) in lettuce matrix,coupled with liquid chromatography-mass spectrometry(LC-MS).
