Simple preparation of glassy carbon electrode

BUNSEKI KAGAKU, 1971
It is recognized that the reversibility of the electrode reaction at the carbon paste electrode is far superior to the glassy carbon electrode. The carbon paste electrode, however, cannot be used for the electrode reaction in nonaqueous solution. In this report, the simple preparation of the glassy carbon electrode, which can be used even in nonaqueous
