ABSTRACT:
A method for measuring the amount of an electroactive gas in a gaseous mixture using an electrochemical cell, the cell including a working electrode (anode), counter electrode (cathode), an electrolyte in which oxygen reduction is inhibited, means for applying a variable potential across the electrodes, and means for measuring current flow between the electrode, the method involving contacting the gaseous mixture with the anode, applying a potential across the anode and cathode and cycling the applied potential between a potential level at which the gaseous mixture adsorbs onto the anode and a potential level at which the adsorbed mixture is oxidized, and measuring the current resulting from the anodic sweep portion of the potential cycle as a measure of the amount of the adsorbed gas in the gaseous mixture.
