Abstract

Ultrafast double potential step chronoamperometry at an ultramicroelectrode was achieved through decreasing the ohmic drop by positive feedback compensation, and the lower limit of the time window was extended to the submicrosecond level. With the reduction of anthracene in acetonitrile as a test system, the validity of this instrumentation was demonstrated by comparing between experimental and simulated curves. The capability in kinetic studies of the technique was then approved.
