摘要： 由于毛细管电泳（CE）和毛细管电色谱（CEC）具有所需样品体积小、分离效率高等特点，越来越多的学者已将它们应用到农药残留（简称农残）检测中，并将它们同各种不同的检测器以及样品浓缩方法相结合，以提高检测的灵敏度。本文对CE和CEC两种方法中所涉及的常见的样品预浓缩方法进行了简要的介绍。对各种不同类型的检测器（如紫外检测、荧光检测、电化学检测以及质谱检测等）的优缺点及其在农残检测中的应用情况进行了评述;同时对手性农药的CE和CEC分离检测情况进行了特别介绍;并对CE和CEC在农残分析与检测中的应用前景进行了展望。

Abstract: Capillary electrophoresis (CE) and capillary electrochromatography (CEC) have some outstanding advantages, such as less sample consumption and high separation efficiency. Coupled with different detection modes, such as ultraviolet detection, laser-induced fluorescence, amperometry, conductometry, mass spectrometry, and various sample preconcentration methods, CE and CEC have been accepted by more and more analysts in the detections of pesticide residues. This review focuses on the comparison of the merits and demerits of various detection modes in pesticide residue detections. The preconcentration methods of pesticide residues have been discussed briefly also. Special attention has been paid on the separation and detection of enantiomeric pesticide compounds. Expectation on the applications of CE and CEC is also outlined.
