摘要：

Capillary electrophoresis (CE) has been recognized as a highly attractive separation technique for determining agrochemical residues in agricultural produces and environmental matrices due to its extremely high column efficiency, rapid analysis, and less reagent consumption. However, a small sample size and a short optical path length make the low concentration samples detected with an ultraviolet (UV) detector difficult or even impossible without sample preconcentration. The on-line concentrating techniques promise to extremely increase sample size without the changes of CE instrument and make the detection of agrochemical residues possible by CE. This review describes these on-line preconcentration techniques and comments their applications in the determination of agrochemical residues.
