Title: Sensor for determining the concentration of oxidizable constituents in a gas mixture

Abstract: A sensor serves to determine the concentration of oxidizable components in a gas mixture, in particular for determining saturated and unsaturated hydrocarbons by measuring the voltage between at least one measuring electrode and a reference electrode. The material for the measuring electrode is based on compounds of the eschynite class, including eschynites, euxenites and samarskites with general formula AB.sub.2 O.sub.6, which have the general empirical formula A.sub.1-x B.sub.2-y B'.sub.y (O,OH,F).sub.6.+-.z and may be partially doped or may have occupancy defects.
