Consists of six words: Quick, Easy, Cheap, Efficient, Rugged, and Safe. It is a sample preparation and purification technology used for the analysis of multi pesticide residues in high humidity foods. The principle is similar to that of high-performance liquid chromatography (HPLC) and solid-phase extraction (SPE), where impurities are adsorbed to achieve purification. The QuEChERS method involves extracting a homogeneous sample with acetonitrile (or acidified acetonitrile), using extraction salts (magnesium sulfate and buffer salts) for salting out and layering. Using the matrix dispersion extraction mechanism, PSA and other adsorbents are combined with the vast majority of interfering substances (organic acids, fatty acids, carbohydrates, etc.) in the matrix, After centrifugation and layering, the upper liquid is taken for analysis to achieve purification purposes. INNOTEGprovides you with cost-effective pre-treatment consumables, including SPE solid-phase extraction columns, QuEChERS products, and chromatographic fillers.
