Rugged GC/MS/MS Pesticide Residue Analysis Fulfilling the USDA Pesticide Data Program (PDP) Requirements
7 Nov 2012
In this application note GC/MS/MS is used for the analysis of pesticide residues in fruits and vegetables. A novel method was developed, optimized and successfully implemented for routine use in a PDP laboratory. The Agilent 7000B Triple Quadrupole GC/MS System enabled sensitive, selective and reliable analysis of pesticide residues in various matrices, including PDP fruit and vegetable samples. Using the Multi-Mode Inlet in PTV solvent vent mode enabled injection of larger volumes of QuEChERS extracts in acetonitrile without affecting analyte peak shapes. Over 70 pesticides were analyzed in a 20-minute run, fulfilling the PDP quality control requirements.
