QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) is a sample preparation technique for the rapid analysis of food and agricultural samples. Ideal for pesticides, veterinary drugs, mycotoxins and more, extraction kits are suited to meet your method of choice.
The first step of QuEChERS is sample extraction using acetonitrile followed by a salting out step to remove water. Agilent offers buffered salts to accommodate various methods, such as Association of Official Agricultural Chemists (AOAC) and European Standard (EN), as well as original (unbuffered) salts. QuEChERS extraction kits feature pre-weighed anhydrous salts in sealed packets to allow salts to be added after adding organic solvent to your sample – avoiding an exothermic reaction that can compromise analyte recovery. QuEChERS extraction kits can be purchased as salt packets only, salt packets with 50 mL polypropylene extraction tubes and caps, or salt packets with 50 mL polypropylene extraction tubes, caps, and ceramic homogenizers. Ceramic homogenizers are effective in breaking up matrix and salt agglomerates for higher extraction recoveries of target analytes. Kits featuring ceramic homogenizers are marked with a CH.
