Abstract: A device for the gas analysis of a gas mixture includes a converter configured to convert a first gas component into a target gas component, a sensor system configured to detect the target gas component or another component of the gas mixture after the conversion by the converter, and an evaluating apparatus. The converter is further configured to change the concentration of a second gas component or to cause a conversion to a second target gas component. The sensor system is configured to determine the concentration of the second gas component or of the second target gas component. The evaluating apparatus is configured to determine a value for the aging of the converter on the basis of the concentration of the second gas component or of the second target gas component.
