| Abstract;A method for calculating the solution resistance of an integrated dual ultramicroelectrode was introduced, and then tested by experiments using dummy cells. Then, with the reduction of anthracene on a gold ultramicroelectrode in a 0.1 M tetraethylammonium tetrafluoroborate/acetonitrile solution as the test system, it could be found that the solution resistance of this integrated dual ultramicroelectrode was much lower than that of the two-electrode system conventionally used. Thus, the compensation level could be improved up to nearly 100% at a scan rate of 1.34 MV s-1, while the latter could not. This showed that the integrated dual ultramicroelectrode was more suitable for acting as the electrode system in ultrafast cyclic voltammetry, especially in a high-resistance solution.
