Potentiostat solution for electrochemical amperometric gas sensor

This study deals with intrinsic parameters of electrochemical amperometric gas sensors with a solid-state polymeric electrolyte. An experimental electrochemical NO₂ sensor based on organic ionic liquid was developed. Subsequently, electrical and mechanical parameters of the sensor were studied and an appropriate potentiostat circuit was designed for the evaluation of a sensor response to the particular gas. The description of the sensor, measurement procedures and results of experiments will be presented in more detail.
