Abstract

A detector arrangement for detection of a measuring gas component in a gas mixture is provided. The arrangement includes a gas analyzer, a first single-layer receiver and a further single-layer receiver, the first single-layer receiver containing the measuring gas component and the further single-layer receiver containing a transverse gas. A concentration of the measuring gas component in the gas mixture is determined from signals delivered by sensors of the single-layer receivers. An evaluating device includes an n-dimensional calibration matrix for obtaining matrix signal values. Signal values of different known concentrations of the measuring gas component in the presence of different known transverse gas concentrations are stored as n-tubules in the evaluating device. The concentration of the measuring gas component in the presence of unknown transverse gas concentrations is determined by comparing n-tuples of signal values thereby obtained with the n-tuples of signal values stored in the calibration matrix.
