摘要
静电场轨道阱(Orbitrap)质谱技术以其优越的高分辨率和高精确质量数的特性,可实现目标物的同分异构体和结构类似物的鉴定以及未知物的筛查和确证。本研究采用线性离子阱静电场轨道阱高分辨组合质谱技术(LTQ-Orbitrap),并采用Qu ECh ERS前处理方法对样品进行提取和净化,建立茶叶和粮食中农药残留的快速筛查确证方法。
The Orbitrap Mass Spectrometry Techniques with the high resolving power and mass accuracy can reliably identify the isomeride and structural analogues of target substance, as well as the unknown cornpound. The LTQ-Orbitrap technique, by using the QuEChERS sample preparation for sample extraction and puritication, was used to establish a last screening and confirmation method for pesticide residue detection in tea and cereal samples.
