Format comparison for dSPE workflow improvements for food testing

The complexity and diverse nature of solid samples in food testing makes method standardisation extremely challenging. Pesticide analysis is firmly centred around traditional QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) salt extraction followed by dSPE (Dispersive Solid Phase Extraction) matrix scavenging. Both techniques are manual, labour intensive and typically difficult to automate. This poster will investigate the performance of various AOAC and EN prescribed dSPE clean up sorbent combinations covering a range of general, waxed, pigmented, and highly pigmented fruit and vegetable matrices. Traditional dSPE comprising loose sorbent will be compared to alternative column flow through formats, ISOLUTE® cSPE, in terms of analyte recoveries, RSDs, signal, matrix and pigment removal as well as processing and workflow advantages.
