Abstract: A gas concentration of a gas may be detected from a gas mixture using gas detectors sensitive to the gas. A gas concentration may be measured by a first gas detector at a first operating temperature, and a first signal characteristic of the measured gas concentration may be provided. An operating temperature of the first gas detector may be changed to a second operating temperature, or a second gas detector having the second operating temperature may be provided. A gas concentration may then be measured at the second operating temperature, and a second signal characteristic of the measured gas concentration may be provided. The gas concentration of the gas from the gas mixture may be determined using a first concentration value allocated to the first signal and a second concentration value allocated to the second signal.

Abstract: A method (500, 600) is described for detecting a gas concentration of a gas from a gas mixture, a plurality of gas detectors (304, 402, 404) sensitive to the gas or one gas detector (304, 404) sensitive to the gas being used in different operating states for this detection, and the method (500, 600) includes a step of providing (502) the gas detector (304, 404), the gas detector (304, 404) having a first operating temperature (310). In a next step of the method (500, 600), the gas mixture is supplied (504) to the gas detector (304, 404), a gas concentration of the gas from the gas mixture being measured by the gas detector (304, 404) at the first operating temperature (310), and a first signal (202) characteristic of the measured gas concentration being provided. In addition, the method (500, 600) includes a step of changing (506) an operating temperature of the gas detector to a second operating temperature (312), which is different from the first operating temperature (310), or providing (602) an additional gas detector (402), the additional gas detector (402) having the second operating temperature (312). In another step of the method (500, 600), the gas mixture is fed (508, 604) to the gas detector (304, 404) or the additional gas detector (402), a gas concentration of the gas from the gas mixture being measured by the gas detector (304, 404) or the additional gas detector (402) at the second operating temperature (312), and a second signal (204) characteristic of the measured gas concentration being provided. Furthermore, the method (500, 600) includes a step of determining (510) a gas concentration of the gas from the gas mixture using a first concentration value allocated to the first signal (202) and a second concentration value allocated to the second signal (204).

Abstract: An arrangement for detecting hydrogen peroxide includes a sample space configured to receive a hydrogen-peroxide-containing gas. The sample space is fluidically connected to a hydrogen-peroxide-selective colorimetric detection reagent. The arrangement also includes at least one radiation source configured to irradiate the detection reagent and at least one detector configured to detect at least one optical property of the colorimetric detection reagent. This arrangement enables detection of hydrogen peroxide in the gaseous phase without the need to transfer hydrogen peroxide to the liquid phase. As a result, a simplified measurement behavior and additionally a highly sensitive measurement are attained.

Abstract: An exhaust system of an internal combustion engine includes a first filter device and a second filter device located downstream of the first. Both filter devices filter soot particles out of the exhaust gas. At least the first filter device has a catalytic material, which promotes an exothermic soot burnoff in such a way that as a result of the corresponding heating up of the exhaust gas, the soot burnoff in the second filter device is set in motion. The materials of the two filter devices are selected such that the soot burnoff in the first filter device ensues at a lower temperature and/or at a similar temperature is stronger than in the second filter device.
