Abstract

Abstract The field of flow electroanalysis is briefly surveyed, emphasizing the common hydrodynamic basis of continuous monitoring, continuous flow and flow-injection analysis and liquid chromatography (LC). Examples of recent developments are given for potentiometric and voltammetric detection. Special attention is paid to the use of ion-selective microelectrodes and large-volume wall-jet cells in potentiometric detection, the use of voltammetric microelectrodes for detection in open-tubular column LC, physical, electrochemical and biochemical modification of solid voltammetric electrodes and application of cells with solid polymer electrolytes to amperometric detection in liquids with very low electrical conductivity.
