Abstract

A method and a gas sensor arrangement for determining an absolute gas concentration with a gas sensor and a decomposing gas to be measured are disclosed. In an embodiment a method includes acquiring a first sensor signal and determining from the first sensor signal at least one initial data point, decomposing the gas to be measured using a means for decomposing the gas of the gas sensor arrangement, acquiring a second sensor signal and determining from the second sensor signal at least one decay data point and deriving an absolute gas concentration from a gas concentration function realized as a mathematical function by evaluating the gas concentration function at least for the at least one initial data point and the at least one decay data point.
