Gas sensor arrangement with a shorter transient response time

摘要

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 as well as on a corresponding gas sensor arrangement. The gas sensor arrangement (100) comprises a radiation-emitting radiation source (102), a gas detection space (104), which, with a measurement gas, which contains at least one analyte to be measured which can be filled, and, at least one of the radiation be detected and detecting means (108), which a of the presence and / or concentration of the analyte dependent on the output signal is generated. In order to achieve a method for measuring as well as a generic gas sensor arrangement, whereby the transient recovery time of the gas sensor arrangement is reduced and thus the reliability of the system can be increased, according to the invention, the radiation source (102) controlled such that it during a transient response phase emits radiation having a first pulse train, to the gas sensor arrangement is in the thermal equilibrium, and during a measuring phase radiation with a second pulse sequence for carrying out the measurement, where the first and second pulse sequence in the pulse duty factor and / or the frequency differ.
