Title: Electrochemical measurement and reactions in highly-resistive solvents
Inventor: SAINI SELWAYAN
IPC: G01N27/30
Filed: 1994-03-25
Abstract: Methods are described that permit the formation of a direct electrochemical interface between electrochemical transducers and highly resistive organic samples. The method is based on a formed ion network on the surface of microelectrodes. Solutes or gases in contacting organic samples enter the electrochemical interface and undergo reaction at the electrode surface. The electrochemical interface permits electrochemical reactions of solutes and dissolved gases directly in highly resistive samples for electrochemical measurements and electrosynthesis of compounds. The method uses a cell of closely spaced microelectrodes covered by an ionically conducting film which contacts the highly resistive sample and which contains an organic electrolyte salt such as a tetraalkyl ammonium salt; tetrabutylammonium toluene-4-sulphonate being preferred.
