Agilent QuEChERS Video Notes 2011

About this manual

The document provides an introduction to the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methodology for multiresidue pesticide analysis. It features Joni Stevens and Ron Majors from Agilent's Chemistries and Supplies Division explaining the process.

The guide details the three primary steps of the method: 1) Acetonitrile salting-out extraction to create an aqueous environment, 2) Liquid-solid extraction using dispersive Solid Phase Extraction (d-SPE) to remove matrix interferences, and 3) Analysis via techniques like LC/MS/MS or GC/MS. It also describes the resulting sample layers and mentions available universal dSPE kits.
