Estimation of 136 pesticide residue in Black Pepper using QuEChERS extraction technique and QSight™ LC-MS/MS

Estimation of pesticide residue in Black Pepper

Introduction

It is very well known that Black pepper is a complex matrix that requires a proper extraction and clean-up method for interferences. In this study, a fast, sensitive and selective multi-residue method has been developed for analysis of over 136 pesticides in Pepper samples by coupling a modified QuEChERS extraction method with LC/MS/MS. Using time-managed- MRM in the QSight triple quadrupole mass spectrometer, the optimum dwell time of multiple MRM transitions can be generated automatically for the targeted analytes. This not only saves time in method development but also improves data quality and analytical performance of instrument.
