Improvement of the sensitivity of a stationary Raman gas analyzer

A prototype of a stationary Raman gas analyzer with the improved sensitivity is described. The improvement is provided by using both a device for compressing analyzed gas media and a specialized effective spectral device as a part of the gas analyzer. The experimental testing of the modified Raman gas analyzer was performed in the probing of atmospheric air that confirmed the extreme sensitivity of the prototype was equal to ~ 1 ppm.
