Dispersive SPRE Clean-up

Behind

Brand

The name QuEChERS, which stands for Quick, Easy, Cleap, Effective, Rugged and Safe, is an effective system for determining pesticide residues in fruits, vegetables and other foods.

The QuEChERS method is a dispersive solid phase extraction (dSPE) system that involves two stages, a first extraction stage, followed by a cleaning or Clean-up phase of the extract, by dispersive solid phase extraction.

2nd Phase: Cleaning and Clean-up Phase

In this phase 2 ml and 15 ml centrifuge tubes are used.

In this Clean-up stage, the extract from the previous phase is cleaned by dispersive solid phase extraction (dSPE), eliminating residual water and other compounds present in the matrix by using different salts and fillers such as MgSO4, primary/secondary amine (PSA), C18, and graphitized black carbon (GCB) depending on the recommended method.

Once the cleaning process is finished, it is centrifuged, evaporated and solvent is added for further analysis.

Teknokroma's QuEChERS Kits are fully adapted to the recommended methods such as EN15662, AOAC 2007.01, or the Mini-multiresidue method.

Salt/adsorbent in sample extraction pouches are available on request (P/N+K) .
