Analysis of Multi-Residue Pesticides in Rice by LC/MS/MS


Due to the large number of pesticides potentially used in rice production, the use of multi-residue methods capable of determining many pesticides in one single run is the most efficient approach. In this study, a fast, sensitive and selective multiresidue method has been developed for analysis of over 200 pesticides in rice samples by coupling a modified QuEChERS extraction method with LC-MS/MS. Using time-managedMRM in the QSight® triple quadrupole mass spectrometer, the optimum dwell time of multiple MRM transitions can be generated automatically for the targeted analytes.
