Abstract

This research was focused on the performance evaluation of a simple sample preparation involving acetonitrile extraction followed by liquid chromatography/mass spectrometry (LC/MS) analysis. Simplified method validation parameters, along with several other features, were compared to those of the citrate QuEChERS for 19 pesticides analyzed in four representative fruits and vegetables. The results showed comparable performances of the two methods for 5 of the 6 investigated validation parameters. The simplified method had better performance regarding the selectivity, since three analytes experienced a selectivity issue in one of four QuEChERS-treated matrices. Overall, results lead to an assumption that acetonitrile extraction could be reasonably implemented in certain cases of pesticide analysis, as an efficient and economical alternative to the official method. Since the research provides an insight into acetonitrile extraction capabilities in the domain of pesticide analysis in complex matrices, scientists, researchers or analytical practitioners can determine which method is most beneficial for a particular analysis.

一步提取法与 QuEChERS 法在特定水果和蔬菜中的农药分析中的比较

这项研究的重点是对简单的样品制备方法进行性能评估，包括乙腈萃取和液相色谱/质谱（LC/MS）分析。针对四种代表性水果和蔬菜中 19 种农药的分析，将简化方法的验证参数以及其他一些特征与柠檬酸盐 QuEChERS 方法的验证参数进行了比较。结果表明，在 6 个调查验证参数中的 5 个参数上，两种方法的性能相当。简化方法在选择性方面表现更好，因为在四种经 QuEChERS 处理的基质中，有三种分析物出现了选择性问题。总之，研究结果表明，在农药分析的某些情况下，乙腈萃取法可以作为正式方法的一种高效、经济的替代方法得到合理应用。由于这项研究提供了对复杂基质中农药分析领域乙腈萃取能力的深入了解，科学家、研究人员或分析从业人员可以确定哪种方法对特定分析最有利。
