摘要
介绍了一种农药多残留快速检测方法 .此方法样品前处理过程简单 ,快速 ,采用固相萃取和氮吹仪实现了样品的净化和浓缩 ;双柱 ,双检测器的仪器配置提高了检测结果的准确度和精密度 .
This paper describes a new analysis method for pesticide residues in fresh vegetables and fruits. The step of the sample preparation is simple and quick. The sample is cleaned up by solid phase extraction and concentrated by the nitrogen evaporator. All the samples are analyzed by gas chromatography and liquid chromatography configured with dual column and dual detector. The results are greatly improved on precision and accuracy.
