Quantitation Enhanced Data-Dependent (QED) Scanning of Drinking Water Samples Using EQuan for PesticideAnalysis on aTriple Stage Quadrupole

Instrument Type: LCMSMS

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.

Detection of Glucocorticoid Residues in Animal-derived Food by HPLC-MS/MS

Instrument Type: LCMSMS

We developed an effective LC-MS/MS method to detect eight gluococorticoid residues in the liver and muscles of pig, cattle, and lamb, as well as in chicken, eggs and milk.
