Multiresidue Analysis of Pesticides in Fruits and Vegetables Using UPLC-MS/MS

In this application note, the development of a multiresidue method for the routine determination of 190 pesticide residues in various fruit and vegetable matrices using UPLC-MS/MS is described. White grapes and green beens were selected for this application due to their relatively increased complexity, since they contain chlorophylls which are known to affect the extraction efficiency of pesticides from food matrices. A generic QuEChERS sample extraction procedure was used to extract the pesticides from the samples, followed by a rapid and high resolution UPLC separation and trace level detection of pesticides using the Xevo TQ-S micro.
