The method uses the Highly Selective Reaction Monitoring (H-SRM) mode of the TSQ Quantum Ultra triple quadrupole mass spectrometer to effectively reduce the background interference and improve the signal-to noise ratios. For the pesticides investigated, satisfactory precision and accuracy were achieved and Limit of Quantitation (LOQ) values of 0.010 mg/kg were established. The method can be expanded to include more pesticides and their metabolites to improve the range of pesticide residues monitored in food commodities.
