The Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method is a straightforward sample preparation technique designed for extracting pesticides and veterinary drugs residues from various matrices including foods, biological fluids and environmental samples. SelectCore QuEChERS Products, including both extraction and dispersive SPE kits, are conveniently pre-packaged with pre-weighed anhydrous salts and sorbents in packets and tubes, in line with regulatory standards.

QuEChERS Dispersive SPE Kits

During extraction, SelectCore QuEChERS extraction kits are added to prevent exothermic reactions, minimize sample degradation, and maximize recoveries. Two primary methods are used:

• EN 15662 (European Committee for Standardization Method) , which uses a citrate buffer for extraction.

• AOAC 2007 (Association of Analytical Communities Official Method) , which uses an acetic acid buffer.

SelectCore QuEChERS extraction kits offer various buffering strengths, promote liquid phase separation, as well as stabilize acid and base labile pesticides.
