Abstract
Triple-barrel carbon filament microelectrodes were chemically and electrochemically oxidized to allow resolution of ascorbic acid from catecholamines during differential pulse voltammetric scans. The contribution of current from DOPAC to the catecholamine signal was minimized by this treatment. These electrodes exhibit linearity over a wide range of concentrations and long-term response stability.
