a multiresidue method for pesticide profiling using an orbitrap tribrid mass spectrometer


An AcquireX workflow implemented on the Orbitrap ID-X Tribrid mass spectrometer was evaluated for the analysis of 250 pesticides spiked into strawberry matrix to demonstrate the efficiency of the workflow for identifying the pesticides spiked at different levels. Detection and identification were determined by matching experimentally acquired MS and MS/MS data to validated spectral libraries. The efficiency of the AcquireX workflow was evaluated against a standard data-dependent acquisition and dynamic exclusion method that did not utilize an exclusion list.
