| 摘要 |
A selective electrochemical method for measuring carbon monoxide in admixture with other electrochemically oxidizable gases, for example, hydrogen, hydrocarbons and oxides of nitrogen, and especially exhaust gases from internal combustion engines, which method comprises supplying the gas mixture to an anodic electrode to oxidize the CO to CO2 while simultaneously supplying an O2 -containing gas to a cathodic electrode to reduce the O2 to O<=>, said electrodes being separated by an electrolyte, and determining the CO content by directly correlating the current which is produced and measured in an external circuit with a known CO standard.
