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.

An optical measuring cell for a gas absorption measurement, comprising:
- a light source for introducing light into a measuring volume;
- a light sensor configured to detect light conducted through the measuring volume, the light sensor being arranged approximately opposing the light source in relation to the measuring volume and in the direction of propagation of the light source;
- an evaluation unit configured to determine a concentration of one or more target gases in the measuring volume;
- and
- a hollow fiber, wherein the measuring volume is represented by an internal volume of the hollow fiber, the hollow fiber having an internal diameter of less than 1 mm.
A gas monitor, comprising:
- an optical measuring cell;
- and
- a gas delivery system;
- wherein the gas monitor is configured to detect and indicate a particular target gas, wherein a positive target gas mixture generates a signal.
