Abstract

A process and apparatus for selective detection of NO in fluid media, particularly exhaust gases of internal-combustion engines. This process comprises the steps of positioning a nitrosonium-conducting solid electrolyte between two porous electrodes, acting upon one of the two electrodes with the NO-containing fluid medium, and measuring a voltage difference between the two electrodes as an indication of the NO-concentration in the NO-containing fluid medium.
