SiliaQuick QuEChERS for Pesticide Residue Analysis

The QuEChERS technique was developed in 2003 by USDA scientists to simplify and accelerate the analysis of pesticides in various fruit and vegetable samples. The name QuEChERS is formed by an acronym of the properties that are observed with this technique: Quick, Easy, Cheap, Effective, Rugged and Safe.

The QuEChERS method has gained in popularity to become the most valuable alternative for determination of traces of analytes in a high throughput environment. Presently, scientists have expanded the use of this method to the analysis of a vast array of pesticides, herbicides, fungicides, antibiotics, drugs, and any other compounds present in all food, beverage, animal and human matrices.

The QuEChERS technique can be summarized as a three-step methodology, starting with a Liquid Extraction, followed by a dispersive Solid-PhaseExtraction clean-up, and completed by a LC or GC Analysis:

  • First step is to carry out the extraction of compounds of interest from your food or beverage matrix through a solvent (mainly acetonitrile).
  • The dispersive Solid-Phase Extraction clean-up is designed to remove specific undesired compounds such as sugars, lipids, organic acids, proteins, pigments and excess water from the solution. 
  • Final analysis step consists in a simple injection into a LC or GC coupled with MS or MS/MS instrument to quantify the analyte concentration.
