| titleOfInvention | Method for measuring the concentration of at least one gas component in a measuring gas |
| abstract | For measuring the concentration of at least one gas component in a measuring gas, the light of a light source is guided along a light path through a measuring volume containing the measuring gas to a detector unit, and the concentration of the gas component is determined from the wavelength-dependent absorption of the light detected there. To this end, the light path is guided outside of the measuring volume through a substitute gas held in a closed volume. In order to ensure, using simple means and with little cost, that the measurement result that is output is not influenced by the ambient air penetrating into the regions of the light path filled with substitute gas, a substitute gas comprising a substitute gas component in a predetermined concentration is used, wherein the substitute gas component is present in the atmosphere and in the measuring gas in a concentration that is not significantly lower than the predetermined concentration, or at a known ratio to the gas component to be measured, the substitute gas is held in the closed volume without constant gas supply and removal, and the concentration of the substitute gas component is monitored on the basis of the detected wavelength-dependent absorption, and in case the decrease in the concentration exceeds a predetermined degree, an error message is generated. |
