Agilent Bond Elut QuEChERS

Agilent Bond Elut QuEChERS kits are easy to use and enable fast sample preparation. Pre-packaged dispersive and extraction kits, extraction salts, and ceramic homogenizers save time and are ideal for application areas such as food, pesticides, and mycotoxins. The QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) technique revolutionized multiresidue, multiclass pesticide analysis and can be performed in a couple of simple steps.

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 extraction tubes, or salt packets with 50 mL extraction tubes and ceramic homogenizers. Ceramic homogenizers are effective in breaking up matrix and salt agglomerates for higher extraction recoveries of target analytes.

The second step of QuEChERS is sample clean-up. The extract from Step 1 is added to a dispersive solid phase extraction (dSPE) tube that is selected based on the specific method and matrix. Dispersive kits contain sorbents and salts and are supplied in 2 mL or 15 mL centrifuge tubes to accommodate the aliquot volumes specified by current AOAC and EN methodologies. Choose from AOAC and EN dSPE kits targeted for a variety of matrices such as: general fruits and veggies, pigmented fruits and veggies, highly pigmented fruits and veggies, fruits and vegetables with fats and waxes, and many more. The Universal dispersive kits provide excellent recoveries and reproducibility for many types of fruits and vegetables.
