摘要: 用气相色谱-质谱联用仪以选择离子检测方式(SIM)对蔬菜中含有的包括有机磷、氨基甲酸酯及拟除虫菊酯类等三类十五种农药的残留量进行定性和定量分析。通过优化色谱条件,缩短了分析时间,通过采用保留时间和特征离子比例进行定性,使得结果更为可靠。结果表明,方法检出限为0.003~0.100mg/kg、回收率在77%~110%之间,变异系数为5%~21%, 能满足多残留农残分析的要求。

Abstract: A new method for the rapid determination of 15 pesticides residue in vegetables by Gas chromatography/Massspectrometry was developed. The analysis time decreased by optimize the operation conditions. The result has more credibilitywhen determine the nature by retain time and the proportion of characteristic ions. The average spiked recoveries ranged from77% to 110%,with the relative standard deviations(RSD) from 5% to 21%.
