TL;DR: The acetate-buffered version of QuEChERS using MeCN exhibited advantages compared to the other tested methods in the study, and worked equally well for all matrices tested.
Journal ArticleDOI
Optimization and validation of a quantitative liquid chromatography-tandem mass spectrometric method covering 295 bacterial and fungal metabolites including all regulated mycotoxins in four model food matrices.
TL;DR: It can be concluded that quantitative determination of mycotoxins by LC-MS/MS based on a "dilute and shoot" approach is also feasible in case of complex matrices.

Overcoming matrix effects using the dilution approach in multiresidue methods for fruits and vegetables.
Carmen María Salvador Ferrer,Ana Lozano,Ana Agüera,A. Jiménez Girón,Amadeo R. Fernández-Alba +4 more
TL;DR: In this work, matrix effects of 53 pesticides in three different matrices were evaluated and a dilution factor of 15 demonstrated to be enough to eliminate most of the matrix effects, opening the possibility to perform quantification with solvent based standards in the majority of the cases.

Properties and determination of pesticides in fruits and vegetables
TL;DR: In this paper, the authors discuss the problems in the determination of organonitrogen and organophosphorus pesticides in samples of fruit and vegetables, including the complexity and the diversity of matrices in biological materials, and the very low level of pesticides present, as a result of which target analytes have to be isolated and then enriched prior to final determination.
Journal ArticleDOI
Liquid chromatography–mass spectrometry in food safety
TL;DR: Main attention in this review is on the achievements that have been possible because of the latest advances and novelties in mass spectrometry and how these progresses have influenced the best control of food allowing an increase in the food safety and quality standards.

Fast and Easy Multiresidue Method Employing Acetonitrile Extraction/Partitioning and "Dispersive Solid-Phase Extraction" for the Determination of Pesticide Residues in Produce
TL;DR: A simple, fast, and inexpensive method for the determination of pesticide residues in fruits and vegetables is introduced and effectively removes many polar matrix components, such as organic acids, certain polar pigments, and sugars, to some extent from the food extracts.
Journal ArticleDOI
Matrix effects in quantitative pesticide analysis using liquid chromatography-mass spectrometry.
TL;DR: Issues related to matrix effects are reviewed, focusing on quantitative pesticide analysis, but also paying attention to expertise with respect to Matrix effects acquired in other application areas of LC-MS, especially quantitative bioanalysis in the course of drug development.

Comparison of an acetonitrile extraction/partitioning and "dispersive solid-phase extraction" method with classical multi-residue methods for the extraction of herbicide residues in barley samples.
TL;DR: QuEChERS method was compared with known conventional multi-residue extraction procedures and resulted to be the most universal extraction method by providing a well-defined phase separation without dilution and achieving acceptable recoveries in average including the extraction of the always difficult acidic herbicides.
