Methods and systems to analyze a gas-mixture

Abstract:

A system is presented. The system includes an electromagnetic radiation source configured to generate a mode matched electromagnetic radiation that irradiates a gas mixture filled in a gas compartment at a determined pressure `P` bars, an intensity enhancement mechanism that internally reflects the mode-matched electromagnetic radiation a plurality of times to achieve an effective intensity `E`, of reflected electromagnetic radiation in a region of interest, that is `N` times an intensity of the mode-matched electromagnetic radiation, and a detection subsystem that analyses the gas-mixture based upon Raman Scattered photons emitted from the region of interest, wherein a product of the `P` and the `N` is at least 30.
