Abstract
A gas cell () for the spectroscopic, in particular absorption spectroscopic, analysis of a gas, in which the gas is exposed to an incident beam of rays (S) of electromagnetic radiation and a beam of rays (S) of electromagnetic radiation exiting the gas is detected to form a measurement signal, wherein the gas cell () comprises a body () formed by a porous, electromagnetic radiation-scattering material, an in-coupling device () for coupling the incident beam of rays (S) into the gas cell () and an out-coupling device () for coupling the exiting beam of rays (S) out of the gas cell (), wherein, according to the invention, the gas cell is further developed according to the invention by forming a material-free cavity () in the body (), which is surrounded by an inner surface () running within the material and is both diffusely reflecting and transmitting the electromagnetic radiation.
