This application note describes a simple and rapid extraction procedure for pesticide residues in lemon essential oils. The method uses Agilent Bond Elut QuEChERS extraction and modified dispersive SPE coupled with GC/MS.
This document details a simple and rapid extraction procedure for pesticide residues in lemon essential oils. The method combines Agilent Bond Elut QuEChERS EN Extraction and AOAC dispersive SPE kits with Gas Chromatography/Mass Spectrometry (GC/MS) analysis. It addresses the challenge of detecting chemicals in citrus essential oils, which are extracted from fruit peels and may contain higher concentrations of pesticide residues than the fruit itself.
