Multiresidue analysis of pesticides in avocado with Agilent Bond Elut EMR—Lipid by GC/MS/MS

Posted: 7 November 2017 | | No comments yet

This study demonstrates the application of this novel product for the analysis of 23 GC-amenable pesticides in avocado by GC/MS/MS.

Agilent Bond Elut Enhanced Matrix Removal—Lipid (EMR—Lipid) is the next generation of sample preparation products, and is used in convenient, dispersive solid phase extraction (dSPE) for highly selective matrix removal without impacting analyte recovery, especially for high-fat samples.

The procedure involves a QuEChERS AOAC extraction followed by EMR—Lipid dSPE and polish salts. EMR—Lipid provides far superior matrix removal by weight, GC/MS full scan, and matrix effect determination when compared to C18/PSA and zirconia-based sorbents. Furthermore, less matrix is introduced into the analytical flow path. The data also demonstrate dramatically improved reproducibility for the analytes over 100 injections relative to C18/PSA and especially zirconia, which experience significant response deviations.
