Eliminating Problematic Matrix Interferences for Robust Analysis of Pesticide Residues, PAHs and Fungicides with Supel™ QuE (Dispersive SPE) for “QuEChERS” Method

In “QuEChERS” methodology, the use of loose extraction salts and cleanup sorbents in combination with shaking and centrifugation results in a Quick, Easy, Cheap, Effective, Rugged and Safe sample cleanup technique. The “QuEChERS” method has emerged as a sample prep technique popular in the area of multi-residue pesticide analysis in food and agricultural products, and is formalized in method EN15662:2008 and AOAC 2007.01. Recently, QuEChERS has been expanded into areas including PAH, PCB, PBDE and flame retardant analysis. This note presents several applications of the Supel Que line for the analysis of chemical contaminants in food matrices.
