Laser Raman spectroscopy technology is a spectral gas analysis technology based on gas Raman scattering. It uses a laser with high beam quality to emit laser light of a specific wavelength, which is focused in the gas chamber through an achromatic lens.

At the focal point, the laser collides with gas molecules to generate Raman scattering. The intensity of the Raman characteristic peak is proportional to the gas concentration value. By measuring and analyzing the position and intensity of the Raman characteristic peak with a spectrometer, simultaneous measurement of multi-component gases can be achieved.

Since the excitation and collection of the Raman scattering spectrum occur instantaneously and in a very short time, and signal collection can be carried out in real-time, compared with chromatography and mass spectrometry, the Raman spectrometer has a faster response speed.
