An individually addressable microelectrode array system has been developed in the course of this work. The performance of this system was investigated using conventional electrochemistry (oxidation/reduction or ferrocene carboxylic acid) to demonstrate that independent potential control and current measurement at each of the array components was possible. The practical utility of this system has been demonstrated using a conducting polymer based microarray detection system subsequent to Ion Chromatography. The detection of simple electroinactive ions (e.g., Cl − , SO 4 2− , K + , NH 4 + ) using the array system was achieved and the response at each of the array components was studied as a function of polymer composition.
