Gas Sensor an overview | ScienceDirect Topics

Gas sensors and biosensors are obtained by fixing an auxiliary chemical or biochemical system over the ISE membrane. The analyte reacts with the auxiliary system with production or consumption of the ion that is sensed by the ISE. Two basic types of gas sensor, the Severinghaus electrode and the ‘airgap’ electrode, are described elsewhere in this encyclopedia. Biosensors consist of a ...
