Abstract

An optical measuring cell for measuring gas absorption with a light source for introducing light into a measuring volume and a light sensor located approximately opposite the light source in the direction of light propagation and relative to the measuring volume for receiving light that is guided through the measuring volume is provided. The concentration of one or multiple target gases in the measuring volume is detected by an evaluation unit. The measuring volume is constituted by an internal volume of a hollow fiber having an internal diameter less than 1 mm.
