Abstract

A sensor system, the manufacturing of such system, and the use of such system for optical detection of a target analyte in a gaseous medium are described. The sensor system includes a hollow waveguide that is provided with a reflective mirror layer along its inner wall and a concentrating coating of an inorganic sorption material. The mirror layer defines a light path for guiding light between a light inlet and a light outlet that are provided on opposing terminal ends of the hollow waveguide. The concentrating coating increases an effective concentration of target analytes, if present, and allows optical, preferably spectroscopic, analysis of the medium by recording transmission of light, preferably infrared light, guided through the hollow waveguide.
