Abstract

A gas sensor arrangement for detecting the presence or concentration of an analyte in a measuring gas comprises a gas measuring chamber having an inlet for receiving the measuring gas. A measuring radiation source is arranged in the gas measuring chamber. The measuring radiation source emits radiation in a non-uniform pulse sequence according to a signal from a controller. A radiation detector receives the radiation emitted from the measuring radiation source. The radiation detector sends an output signal to the controller for processing.
