Wide Range And Improvements Of QuEChERS

QuEChERS is a streamlined technique that makes it easier and cheaper for analytical chemists to examine the pesticide residues in agricultural products. It is exploited by many professors of the American Ministry of Agriculture in 2003, especially Anastassiades. This technique shares the same principle with high-performance liquid chromatography and solid-phase extraction. That is the interaction between the impurities in the sample and the adsorbent.

Basic steps:

The basic steps of QuEChERS can be included in several points.
1. Thoroughly grind the sample
2. Acetonitrile single solvent extraction and separation
3. Add salts to dehydrate, such as MgSO4
4. Add adsorbent to remove impurities
5. Detect by GC-MS、LC-MS
