Application Note: Quantitation Enhanced Data-Dependent (QED) Scanning of Drinking Water Samples Using EQuan for Pesticide Analysis on a Triple Stage Quadrupole
3 Jul 2007

In recent years, the use of LC-MS/MS for pesticide analysis has become increasingly popular due to the amenability of electrospray ionization (ESI) for polar compounds. This application note describes the Multi-residue assay of a group of pesticides in drinking water by EQuan. The method utilizes SRM for Quantification, followed by Data Dependent™ QED MS/MS and library searching for the structural confirmation of these analytes.
