Abstract
The advantages of microelectrodes such as the improvement of signal‐to‐noise ratio, the ability to perform electrochemical measurements in high resistive solutions and small RC‐time constants give the possibility of an extended use for voltammetric and chronoamperometric techniques in analytical chemistry. In this comparative study, the microelectrode properties of three selected electrodes were examined. The characterization of a RAM‐microarray electrode, an epoxy‐impregnated carbon electrode and a conventional glassy carbon macroelectrode was performed by cyclic voltammetry at different scan rates, by DP‐voltammetric measurements using different concentrations of supporting electrolyte and by transient measurements. It could be shown, that in comparison to the microarray electrode and to the glassy carbon macroelectrode, respectively, the results obtained by using the epoxy‐impregnated carbon electrode are caused by its semimicroelectrode character.
