CUBIC-Laser Raman Spectroscopy Gas Analyzer LRGA-3100
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.
Applications
| • Natural Gas • Natural gas cracking • Shale gas • Mud logging • Petrochemical • Coal chemical industry • Coal to Glycol • Raw coal gas • Inlet of pretreatment • Conversion gas composition • Ferrous Metallurgy |
• Argon blowing in steel ladle
• Mixed gas of Blast Furnace, Coke Furnace and Converter Furnace • Coke oven gas |
- Online real time measurement with wide detection range from 0.1 and 100%.
- One instrument can provide gas monitoring for whole industrial process gases.
- No carrier gas and calibration gas are required with low operating cost.
- Use the baseline-separated peaks to analyze different components which is similar to chromatogram analysis.
- Capable of mounting online in harsh process conditions of high temperature and high pressure with proper gas conditioning system.
- Online measure multi-components gas, including N2, O2, H2, CL2, CH4, C2H6, C3H8, H2S etc., with the shortest response time in seconds.

OEM (Unbranded) refers to industrial components that do not have a publicly identified manufacturer or are delivered through general OEM supply channels without official branding. These products are widely used in industrial automation, machinery diagnostics, vibration monitoring, control systems, and general-purpose engineering applications where performance is defined by specifications rather than brand identity. OEM components are chosen for their practicality, compatibility, and availability across oil & gas facilities, petrochemical plants, power generation units, marine operations, and heavy industrial environments. Seven Star LLC supplies genuine OEM (Unbranded) components for industrial projects across Oman and the Middle East.
