Monitoring environmental pollutants by microchip capillary electrophoresis with electrochemical detection

During the past decade, significant progress in the development of miniaturized rnicrofluidic systems has Occurred due to the numerous advantages of microchip analysis. This review focuses on recent advances and the key strategies in microchip capillary electrophoresis (CE) with electrochemical detection (ECD) for separating and detecting a variety of environmental pollutants. The subjects covered include the fabrication of ruicrofluidic chips, ECD, typical applications of microchip CE with ECD in environmental analysis, and future prospects. It is expected that microchip CE-ECD will become a powerful tool in the environmental field and will lead to the creation of truly portable devices. (c) 2005 Elsevier B.V. All rights reserved.
