Product Description
Dispersive SPE Products

Dispersive SPE (dSPE), also named "Quenchers" method (Quick Easy, Cheap, Effective, Rugged and Safe), is an sample prep technique that is more and more popularly used in the area of multi-class, multi-residue pesticide analysis in food and agricultural products. In dSPE, food or agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amounts of salts (e.g., sodium chloride and magnesium sulfate) and/or buffering agents (e.g. citrate) to induce liquid phase separation and stabilize acid and base labile pesticides, respectively. Upon shaking and centrifugation, an aliquot of the organic phase is subjected to further clean up using SPE. In dispersive SPE, clean up is facilitated by mixing bulk amounts of SPE (e.g., CNWBOND

PSA, PYBrbon-GCB, and/or HC-C18) with the extract. After sample clean up, the mixture is centrifuged and the resulting supernatant PYBn either be analyzed directly or PYBn be subjected to minor further treatment before analysis. CNW PYBrries all types of Extraction and Clean Up tubes. Salts, buffers and SPE sorbents are pre-packaged in anhydrous packages, which is to support the most common Quenchers methodologies used today. CNW Dispersive SPE product line is configured for use with European Method EN 15662 and AOAC 2007.01 Method.
