Abstract

We present a simple method for extracting avermectines from meat, based on a QuEChERS approach followed by liquid chromatography (LC) coupled to triple quadrupole (QqQ) tandem mass spectrometry (MS/MS). The compounds considered are ivermectin, abamectin, emamectin, eprinomectin, doramectin and moxidectin. The new method has been fully validated according to the requirements of European Decision 657/2002/CE (EU, 2002). The method is suitable for the analysis of avermectins at concentration as low as 2.5 μg kg(-1), and allows high sample throughput. In addition, the detection of avermectins by high resolution mass spectrometry using a quadrupole-Orbritrap (Q-Orbitrap) hybrid instrument has been explored, and the target Selected Ion Monitoring data dependent MS/MS (t-SIM-dd MS/MS) mode has been found to provide excellent performance for residue determination of target analytes.Copyright © 2015 Elsevier Ltd.
