How Oxygen, Electrochemical Toxic, and Metal Oxide ...

Hydroxyl ions in turn oxidize the lead (or zinc) anode: ... The oxidation of carbon monoxide in an electrochemical sensor provides a good example of the detection mechanism: Carbon monoxide is oxidized at the sensing electrode: CO + H2O → CO2 + 2H+ + 2e The counter electrode acts to balance out the reaction at the sensing electrode by reducing oxygen present in the air to water: 1/2 O2 ...

The Theory Behind Carbon Monoxide Electrochemical Sensors ...

· The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a nonmetalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference electrode, and the counter electrode. The most important of these is the working electrode (WE). The working electrode is made of platinum, which …

Operating principle ‐Electrochemicaltype gas sensor

Figaro Electrochemicaltype gas sensor are amperometric fuel cells with two electrodes. The basic components of two electrode gas sensors are a working (sensing) electrode, a counter electrode, and an ion conductor in between them. When toxic gas such as carbon monoxide (CO) comes in contact with the working electrode, oxidation of CO gas will occur on the working electrode through chemical ...
