Gas sensor arrangement and measuring method for improving long-term stability |
摘要 |
The present invention relates to a method for measuring the presence and/or the concentration of an analyte by a gas sensor arrangement (100) and relates to a corresponding gas sensor arrangement. The gas sensor arrangement comprises at least a first radiation source (102) emitting radiation (116) and at least a second radiation source (103) emitting radiation (117). A gas measuring chamber (104) may be filled with a gaseous analyte (110) containing at least one analyte to be measured. At least one detector (108) detects the radiation and generates a mostly electric output signal, which depends on the presence and/or the concentration of the analyte. The first radiation source is operated as a reference radiation source, and the second radiation source is operated as a measuring radiation source. After a predetermined service life of the gas sensor arrangement, the operation of the first and second radiation sources is interchanged. |
