Voltammetry with Microscopic Electrodes in New Domains

R. MARK WIGHTMAN 1

1 Professor of chemistry at Indiana University, Bloomington, IN 47405.

Voltammetric electrodes of microscopic dimension, termed ultramicroelectrodes, can be used to make measurements that are difficult or impossible with conventional electrochemical techniques. Measurements of chemical concentration can be made with these electrodes on a microsecond time scale and with micrometer spatial resolution. In addition, measurements can be made in highly resistive solutions.
