一般描述

分散SPE法，通常也是指"QuEChERS” 方法（快速，简便，便宜，有效，耐用和安全），是一种现代样本准备技术，正在越来越多地被用在食品和农业产品多残基杀虫剂分析领域。

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。

应用

Supel^™ QuE is ideally used as an extraction tube for the clean-up procedure involved in the analysis of pesticide residues in agricultural matrices using gas-chromatography coupled to tandem mass spectrometry.

适用性

适用于脂肪、叶绿素和类胡罗卜素含量低的食品/农产品样品。在初始食品萃取和相分配之后，特别适用于净化 6mL 提取液。

Comparison of QuEChERS sample preparation methods for the analysis of pesticide residues in fruits and vegetables.

Steven J Lehotay et al.

Journal of chromatography. A, 1217(16), 2548-2560 (2010-02-11)

This article describes the comparison of different versions of an easy, rapid and low-cost sample preparation approach for the determination of pesticide residues in fruits and vegetables by concurrent use of gas and liquid chromatography (GC and LC) coupled to

Streamlined sample cleanup using combined dispersive solid-phase extraction and in-vial filtration for analysis of pesticides and environmental pollutants in shrimp.

Lijun Han et al.

Analytica chimica acta, 827, 40-46 (2014-05-17)

A new method of sample preparation was developed and is reported for the first time. The approach combines in-vial filtration with dispersive solid-phase extraction (d-SPE) in a fast and convenient cleanup of QuEChERS (quick, easy, cheap, effective, rugged, and safe)
