Microvoltammetric Electrodes.
Abstract
Microvoltammetric electrodes, electrodes of micrometer dimensions, have opened many new domains for electrical investigations. These include increased temporal resolution, increased current density, and decreased sensitivity to the effects of solution resistance. Dramatic improvements in electrochemical data can be obtained with these electrodes. A number of different areas have been investigated with the emphasis on obtaining data that is inaccessible with electrodes of conventional size. Successfully completed projects include measurement of transient electrogenerated intermediates on a microsecond time scale, the use of electrochemistry in highly resistive media such as solutions of benzene, and a characterization of the mass transport processes operant at these electrodes. In addition, the analytical opportunities of microvoltammetric electrodes have been explored, especially as liquid chromatographic detectors.
