摘要
建立了韭菜中11种氨基甲酸酯农药残留的液相色谱串联质谱分析方法,本试验对2种前处理方法(农业部761—2008前处理法、QuEChERS前处理法)进行考察,线性范围在0.5~50.0 ng/mL,线性相关系数0.991~0.999。使用Agilent Bond Elut QuEChERS试剂盒以及NY/T761-2008的前处理方法分别对韭菜进行前处理,QuEChERS方法、农业部761前处理方法的回收率分别为71.23%~100.37%、70.49%~108.32%。结果表明,QuEChERS方法具有操作简便快速、准确率高、重复性好等优点。
Liquid chromatography-tandem mass is set up to analyze the 11 carbamate in garlic chives.This experiment investigated two kinds of pretreatment methods （The ministry of agriculture in 761-2008 before treatment, QuEChERS before treatment ）.The linear range was 0.5-50.0 ng/mL, with correlation coefficients between 0.991-0.999.Used Agilent Bond Elut QuEChERS and NY/T 761-2008 pretreatment method pretreated garlic chives,Then recovery rate by QuEChERS was between 71.23%-100.37%, and NY/T 761-2008 was between 70.49%~108.32%.The results show that QuEChERS pretreatment method is simple accurate and repeatability.
