QuEChERS方法在农药多残留检测中的应用研究进展

QuEChERS方法作为一种农药多残留前处理方法,由于具有快速、简单、廉价、有效、可靠、安全的特点而成为了研究的热点。随着气相色谱(GC)、液相色谱(LC)及气相色谱-质谱(GC-MS)和液相色谱-质谱(LC-MS)联用仪器的不断研发改进,其高效的分离能力和定性鉴定能力结合QuEChERS前处理方法,可在短时间内实现对几十种甚至上百种复杂化合物的分离、定性及定量。重点综述了近年来QuEChERS方法在农药多残留检测前处理方面的应用,详细评述了在样品处理、提取、净化及提取液浓缩等方面对QuEChERS方法进行优化改进的研究进展。

Research progress of QuEChERS method in pesticide mult-residue analysis

QuEChERS,which stands for "quick,easy,cheap,effective,rugged and safe",has been becoming a popular means of sample preparation method globally.Using this method mainly based upon gas chromatography(GC) and liquid chromatography (LC) coupled with mass spectrometry (MS) and MSⁿ as the detection tools for identification and quantification,hundreds of pesticide residues could be measured at parts per billion levels or even below in short time.The historical development and progress of QuEChERS methods in multi-pesticides residue analysis were summarized.The method optimization processes were discussed,such as sample preparation,extraction/partitioning,clean-up,concentrate supernatant and so on.
