一般說明
使用QuEChERS方法,食品/农产品样本首先在水溶性溶剂(比如乙腈),在高盐(比如氯化钠和硫酸镁)和或者缓冲试剂(比如柠檬酸盐)存在下,进行提取。高盐能够引起液相分离,而缓冲试剂能够稳定酸碱不稳定杀虫剂。 在摇晃和离心之后,有机相部分就进一步用SPE清洁。 和传统的SPE管方法不同,在分散SPE中,清洁需要混合大量的SPE(比如Supelclean PSA, ENVI-Carb, 和或者Discovery DSC-18)和提取物。 在样本清洁后,混合物经过离心,得到的上清可以直接分析,或者在分析前需要很少的处理。
Supelco有一系列的管和离心管,含有预置量的盐和SPE吸附剂,能够支持现今最常用的方法。

实验方案
Supelco's Z-Sep+ sorbent effectively removes fat and pigment interferences from avocado, with good pesticide recoveries; it removes more matrix than traditional PSA/C18 sorbent, and produces a lower background for GC-MS analysis.
A highly selective and sensitive analytical method was developed for chloramphenicol using a QuEChERS type sample preparation approach and LC-MS/MS detection.
