chemical gas sensor

Electrochemical gas sensor Wikipedia

Electrochemical gas sensors are gas detectors that measure the concentration of a target gas by oxidizing or reducing the target gas at an electrode and measuring the resulting current. History. Beginning his research in 1962, Mr. Naoyoshi Taguchi became the first person in the world to succeed in the development of a semiconductor device that could detect low concentrations of combustible and ...

Introduction To Electrochemical Sensors Chemistry LibreTexts

· Gas chromatography and electrochemical gas sensors are common examples of this technique. Like other sensors, gas sensors also require a sample and receptor to acquire and analyze measurements 1 ; a good example of this are semiconductor gas sensors, where a gas interacts with the metal oxide surface and the subsequent analysis is made on the basis of whether that gas is …
