Abstract
A versatile microcomputer-controlled electrochemical system for data acquisition and analysis was constructed. The system is presently programmed for cyclic and normal pulse voltammetry, and can be used with other transient electrochemical techniques with a slight modification of the programme for data acquisition. The system can also be used with fast transient techniques; cyclic voltammograms were recorded at scanning rates of up to 1200V s-1. The response of the system was examined by monitoring of the fast electrochemical reactions of quinone/ semiquinone systems, and the collected data were analyzed by finite difference methods. The system could work with a microelectrode assembly, and the signal-to-noise ratio was high enough.
