1 Electrochemical sensors

1 Electrochemical sensors These sensors employ redox reactions to quantify the amount of an analyte. The current flowing through the system or the potential difference between the electrodes as a result of the oxidation and reduction reactions involving the analyte are used for its quantification in the sample. The electrochemical sensors do not suffer from the drawbacks of optical sensors ...

Toxic gas detection Electro-chemical cell | Helloinstru ...

Electrochemical-type 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 reaction ...

The Theory Behind Carbon Monoxide Electrochemical Sensors ...

· Since electrochemical sensors work with the same theory but different materials, we have described only how the CO sensor works in this application note. The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a non-metalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference ...
