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 challenges with electrochemical NO2 sensors in outdoor ...

22/07/2018· A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses other than the target gas. This is called “cross-sensitivity” and is a result of the interfering gas also reacting on the sensor electrode.

How Do Electrochemical Sensors Work? - Analytical ...

17/03/2021· An electrochemical sensor is made up of a "working" electrode, a "counter" electrode, and usually a "reference" electrode. All of these components sit inside of a sensor housing along with a liquid electrolyte. At the top of the housing, there is a mechanism made up of a membrane and a diffusion limiting outlet. This outlet allows the outside air to interact with the liquid electrolyte. A few ...
