Abstract

In this work the design, construction, control and applications of a computerized portable multichannel detection system suitable for electrochemical measurements was developed. The detection system is based on integrated eight homemade miniature potentiostat powered by two 9V batteries. The electrochemical control programme, developed in LabVIEW 6.0, generated the modulation signal, scanned the potential of the working electrode, acquired the current and displayed the results in the form of a voltammogram. The small dimensions, battery operation and inexpensive electronic components make this electrochemical detection system ideal for in situ or field measurements. The utility of the detection system was assessed for the simultaneous determination of four biosensors response to potassium ferricyanide by amperometric and cyclic voltammetry method.
