Determination of benzoylurea and bishydrazide pesticide residues in vegetables by ultra performance liquid chromatography-tandem mass spectrometry with matrix solid phase dispersion
基质固相分散-超高效液相色谱-串联质谱法检测蔬菜中残留的苯甲酰脲类和双酰肼类杀虫剂

A method for the determination of nine pesticides including benzoylureas (diflubenzuron,chlorobenzuron,triflumuron,teflubenzuron,flufenoxuron,chlorfluazuron,hexaflumuron) and bishydrazides (methoxyfenozide,tebufenozide) in vegetables was developed by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) with matrix solid phase dispersion.The sample was graphitized with neutral alumina as dispersant and carbon black as purifying,and eluted with ethyl acetate.The separation was achieve...
