Abstract (en)
[origin: WO2016012407A1] A method for detecting nitrogen oxides in a gas mixture, in which a gas sensor is used which comprises an oxygen ion conductor and at least two electrodes arranged thereupon, the gas sensor is connected with the gas mixture in such a way that both electrodes contact the gas mixture; a polarization voltage or a polarization current is applied to the electrodes during a polarization time period; the current or the voltage at the electrodes is measured during a depolarization time period following the polarization time period; the nitrogen oxide content in the gas mixture is determined from the measured voltage or the measured current; the polarization time period is ended as soon as a specifiable charge amount has flowed since the beginning of the polarization time period.
