Abstract
An electrochemical sensor for measuring relative concentrations of reactive species in a fluid mixture with a first catalytic enclosure for bringing the fluid mixture into thermodynamic equilibrium, and a second enclosure having an electrochemical cell which is responsive to an excess of one of the reactive species with respect to stoichiometry of the reaction. Additional structure for selectively impeding the transfer of species of the fluid mixture to be analyzed are located upstream of or combined with the first enclosure and serve to modify the ratio of relative concentrations of the reactive species of the fluid mixture in predetermined proportions.
