摘要：An electrochemical sensor capable of determining the partial pressure ofvarious gases (e.g., CO, CO.sub.2, H.sub.2 S, alcohol vapors, hydrocarbons, NO.sub.x, etc.)and, optionally, substantially concurrently, but independently, oxygen content in gasesand liquids. The sensor measures the amount of chemisorbent species formed eitherelectrochemically by partial reduction (such as \"Reduced-CO.sub.2 \" in the case ofCO.sub.2) or partial oxidation (in the case of alcohol) or non-electrochemically via specificadsorption (in the case of CO and hydrocarbons) on platinum or other metals. The chargerequired to oxidize this chemisorbed species is proportional to the amount of adsorbateon the electrode surface which is made a reproducible and reliable function of the partialpressure of the gas to be measured. By the proper selection of the sensor constructionand electrical parameters, high sensitivity, fast response time, and high selectivity can beobtained.
