ABSTRACT:
Electrochemical sensor for the concentrations of species in a fluid mixture comprising a measuring cell of the type having a partial pressure internal reference electrode incorporating a catalysis region in which the gaseous mixture is brought into thermodynamic equilibrium and functioning according to the so-called "assay" process, so that only a small quantity of the gaseous mixture to be analyzed is admitted into the sensor. It also comprises a supplementary cell functioning as an ionic pump, so as to continuously modify the composition of the gaseous mixture admitted into the sensor under the control of a regulatable electric current.
