The QuEChERS Method in Sample Preparation

Quick, Easy, Cheap, Effective, Rugged, and Safe - this is what the new method in sample preparation stands for. Developed in 2002, the QuEChERS method has been readily accepted by many pesticide residue analysts. Initially, the methodology was developed for the analysis of veterinary drugs (anthelmintics and thyreostats) in animal tissues but after realizing its great potential in the extraction of polar and particularly basic compounds it was also tested on pesticide residue analysis in plant material with great success. Today, QuEChERS is used in modern laboratories all over the world. Lab efficiency is improved not only with respect to labor reduction and consumable savings but also in terms of higher sample throughput and reduced waste generation and space requirements. If you have any questions on QuEChERS or the products you can find here, please feel free to contact us.

Advantages of the QuEChERS procedure

The QuEChERS procedure entails a number of simple analytical steps and is thus fast and easy to perform and little susceptible to errors. QuEChERS provides high recoveries for a very broad scope of pesticides belonging to various chemical classes and the final extract, being solved in acetonitrile, gives full flexibility in the choice of the determinative analysis technique. Direct connection with liquid chromatography (LC) and gas chromatography (GC) is possible.
