Capillary electrophoresis for the determination of pesticide residues

Capillary electrophoresis (CE) is becoming an advantageous tool for determining pesticide residues in environmental matrices because of its simplicity and high separation efficiency. However, inadequate limits of detection (LODs) and a lack of selective detectors limit the technique. The present review gives an overview of current developments in off-column and on-column approaches to trace enrichment in analysing real samples, and summarises the determination of pesticides residues by conventional CE as well as by the emerging techniques, such as CE-mass spectrometry (MS). The usefulness of these approaches in environmental applications is documented. (C) 2003 Elsevier Science Ltd. All rights reserved.
