Estimating the term…
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.
A method for measuring the presence or the concentration of an analyte by means of a gas sensor arrangement with at least one radiation-emitting radiation source, a gas measuring chamber, which may be filled with a test gas comprising 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 or concentration of the analyte, comprising the steps of:
Gas sensor arrangement comprising at least one radiation-emitting radiation source, a gas measuring chamber, which may be filled with a test gas containing to be measured for at least one analyte, at least one radiation-detecting detector device, which generates an output signal as a function of the presence or the concentration of the analyte, a controller for activating the radiation source, and a heating device for heating the gas measuring chamber, such that a wall of the gas measuring chamber assumes a temperature, which is higher than the dew point of the test gas.
