摘要:
Example embodiments relate to a device for measuring nitrogen monoxide in exhaled air by a gas sensor unit with at least one gas sensor. A device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide may be included. The device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide includes a non-consuming catalyst for catalyzing the oxidation of nitrogen monoxide to nitrogen dioxide.
摘要:
The disclosure relates to an operating method for a gas sensor, in particular a gas sensor for detecting asthma. According to said method, nitrogen monoxide or nitrogen dioxide is detected in a measuring phase and the gas sensor is heated by a heating device in a desorption phase in order to accelerate desorption. The heating process is continued until the temporal alteration of the measuring signal of the gas sensor falls below a threshold value.

摘要:
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.
