Abstract

A method for the determination of pesticides in vegetables by high performance liquid chromatography-heated electrospray ionization tandem mass spectrometry was developed.After extracted by acetonitrile and cleaned up by solid phase extraction,the samples were detected in SRM mode and quantified.The results indicated that the developed method is easier,faster and more sensitive.The linear range,recovery,precision and limits of detection can meet the requirement of residue analysis.
