Supel^™ QuE QuEChERS tube

The Supel^™ QuE PSA/ENVI-Carb^™ Tube 3, 15 mL (clean-up tube) is suitable for the testing workflow of 16 PFAS compounds in food according to regulated FDA method C_01.02. Prior to analysis by LC-MS/MS, a sample preparation is required by the "QuEChERS" method. The QuEChERS method (Quick, Easy, Cheap, Effective, Rugged, and Safe), has emerged as a sample prep technique popular e.g. in the area of matrix rich samples, like food product. In a first step, food sample is extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amounts of extraction salts to induce liquid phase separation. Upon shaking and centrifugation, an aliquot of the organic phase is subjected to further cleanup step. The second step is facilitated by mixing bulk amounts of sorbent (e.g., Supelclean^™ PSA, ENVI-Carb^™, MgSO4) with the extract. After sample cleanup, the mixture is centrifuged and the resulting supernatant can, depending on the sample, either be analyzed directly or can be subjected to further minor treatment before analysis.
