Abstract
A method and a sensor element are provided for determining the concentration of an oxidizable gas in a gas mixture, e.g., in exhaust gases of internal combustion engines. Within the sensor element of a gas sensor, nitrogen oxides, hydrogen, and/or carbon monoxide contained in the gas mixture are at least partially removed in an initial step. In a further step, the concentration of the gas to be detected in the gas mixture freed of nitrogen oxides, carbon monoxide and/or hydrogen is ascertained.
