Abstract
The present invention relates to a method for measuring the presence and/or the concentration of an analyte by means of a gas sensor arrangement and to a corresponding gas sensor arrangement. The gas sensor arrangement comprises a radiation-emitting radiation source, a gas measuring chamber, which may be filled with a test gas containing at least one analyte to be measured, and at least one radiation-detecting detector device which generates an output signal as a function of the presence and/or the concentration of the analyte. In order to be able to reduce the harmful effects of condensation water, which condenses in the gas measuring chamber, the gas measuring chamber according to the invention is heated before the measurement process, such that the wall of the gas measuring chamber assumes a temperature which lies above the dew point of the test gas.
