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 SPE Kits

SelectCore QuEChERS dispersive SPE kits contain pre-weighed PSA/C18/GCB sorbent blends that help to remove matrix interferences from samples.

• MgSO₄ removes residual water and improves analyte partitioning.

• PSA removes sugars, fatty acids, organic acids, lipids and polar pigments.

• C18 removes long-chain fatty compounds, sterols, and other nonpolar interferences.

• GCB removes pigments, polyphenols, and other polar compounds.

After clean-up, the sample mixture is centrifuged, and the supernatant can be analyzed directly or undergo minor additional treatment before analysis.
