Blurton, K F; Sedlak, J M

Noxious gases are electrochemically detected and measured in the presence of carbon monoxide using a device employing an electrochemical cell whose sensing electrode comprises a carbon supported gold catalyst and is maintained at a fixed potential of about 0.4 volt to about 1.5 volt with respect to a reversible hydrogen electrode in said electrolyte of the electrochemical cell. In its preferred form the sensing electrode comprises carbon particles containing catalytic amounts of gold bonded to a hydrophobic material to provide a diffusion electrode.
