Simplified technique for the preparation of glassy carbon electrodes

Abstract

Glassy carbon electrodes, encapsulated in a chemically inert Teflon FEP resin, have been prepared. The preparation of these electrodes is simple, fast and inexpensive. These electrodes are believed to be better suited than wax- or epoxy-impregnated electrodes when used in organic electrolytes or hostile environments. Electrodes prepared in this manner were found to be free from memory effects and leakage. Three identically prepared electrodes were found to behave similarly, facilitating the comparison of data obtained from different electrodes. These electrodes can be used in the evaluation of electrocatalysts, as sensors and in conventional voltammetric analyses.
