Performances of Quechers Based Gc-Ms and Lc-Ms/Ms Methods for Pesticides Analysis in Apples
2024
Anđelković, Darko | Branković, Milica
The diversity and complexity of fruits and vegetables content remains the main challenge in pesticides monitoring in these matrices. At this point, the established sample preparation method is QuEChERS and its two modifications - the acetate-buffered version or AOAC 2007.01 certified method and the citrate-buffered version or EN 15662 certified method. The aim of the study was to evaluate the performances of both QuEChERS modifications, followed by the two most common analytical techniques in pesticides analysis in complex matrices, GC-MS and LC-MS/MS. A review of methods validation parameters confirms that mass spectrometry-based methods combined with the two established QuEChERS sample preparation procedure modifications have satisfactory selectivity and sensitivity for the analysis of pesticides in complex samples.
