Sample preparation for pesticide residue analysis with the QuEChERS method

The so-called QuEChERS method (“quick, easy, cheap, effective, rugged and safe”) was developed by Michelangelo Anastassiades (Chemical and Veterinary Investigation Office CVUA, Stuttgart, Germany) to make sample preparation to pesticide residue analysis more efficient. It basically consists of three steps: Homogenization – Extraction – Analysis. Test series have proved that the analysis results obtained with the QuEChERS method can easily compare with more common methods, such as DFG S19. Various RETSCH instruments are used for the sample preparation process.
