Abstract: An optical absorption gas analyser for determining the concentration of a target gas in a sample is disclosed. The analyser comprises a chamber for containing the sample in use; a radiation source assembly arranged to emit radiation into the chamber; a first radiation detector assembly arranged to detect radiation transmitted along a first optical path through the chamber and a second radiation detector assembly arranged to detect radiation transmitted along a second optical path through the chamber, wherein the length of the second optical path which the sample can intercept is shorter than that of the first optical path. The analyser further comprises a processor adapted to generate a sensing signal SS based on the detected radiation transmitted along the first optical path and a reference signal SR based on the detected radiation transmitted along the second optical path. The processor determines the concentration of the target gas in the sample based on a comparison of the sensing signal with the reference signal.

Abstract: In one aspect of the disclosure, a gas sensor is provided, comprising: a chamber for containing a gas sample in use, and a radiation source adapted to emit radiation within a first waveband. A photoluminescent material, upon absorption of radiation of a first wavelength within the first waveband, emits radiation of a second wavelength, the photoluminescent material being responsive to the presence of a target gas species in the gas sample. The gas sensor further comprises a luminescence detector assembly. The luminescence detector assembly is adapted to detect radiation of the second wavelength and output a corresponding measurement signal related to the concentration of the target gas species. An optics assembly is adapted to receive radiation emitted by the radiation source and to converge the radiation towards a location at which the luminescence detector assembly cannot receive radiation.
