Laser Raman Spectroscopy Gas Analyzer


LRGA-3100 Laser Raman Spectroscopy gas analyzer is independently researched and developed by Cubic Instruments (a wholly-owned subsidiary of CUBIC Sensor and Instrument Co., Ltd). Based on the LRGA-6000--a special product for the development of national significant scientific instruments and equipment, the optical path and structure were optimized to greatly reduce the size of the gas analyzer, so the new generation laser raman gas analyzer is much more compact and transportable. Based on the principle of laser Raman scattering, which enhances, collects, processes and identifies the characteristic Raman scattering spectra of the gas to be measured and quantifies the content, LRGA-3100 can provide online real time measurement for various gases simultaneously with the shortest response time in seconds.
