GC/MS选择离子模式农药多残留检测

THE GC/MS CHOICE ION PATTERN AGRICULTURAL CHEMICALS REMAIN EXAMINATION

农产品安全问题一直是人们十分关注的大问题,本文介绍了采用GC/MS选择离子模式(SIM)进行水果和蔬菜中多类多种农药残留的分析测定。农药的确证和定量依据保留时间和相应定量离子、定性离子及其离子比。对该方法进行了添加回收率实验,平均回收率在70%和120%之间。

The agricultural product security problem always is the major problem which the people pays attention extremely.This article introduced uses The GC/MS choice ion pattern （SIM） carries on in fruit and vegetable for kinds of pesticide residue analysis determination. Agricultural chemicals proof and quota basis retention time and corresponding quota ion, qualitative ion and its ion ratio has carried on the increase returns-ratio experiment to this method, average returns-ratio between 70 % and 120 %.
