Cubic LRGA-3100 Laser Raman Spectroscopy Gas Analyzer
Overview
The Cubic LRGA-3100 Laser Raman Spectroscopy Gas Analyzer is a highly advanced, next-generation analytical instrument independently researched and developed by Cubic Instruments (a wholly-owned subsidiary of CUBIC Sensor and Instrument Co., Ltd). Building upon the foundation of the LRGA-6000—a product developed for significant national scientific applications—the optical path and internal structure of the analyzer have been meticulously optimized. This optimization drastically reduces the overall size of the gas analyzer, making the analyzer an exceptionally compact and transportable solution for modern industrial environments.
As the official authorized partner and exclusive regional representative for Cubic, Seven Star LLC proudly supplies the analyzer throughout the Sultanate of Oman and the wider GCC region. We ensure that industrial facilities, petrochemical plants, and scientific laboratories receive genuine, state-of-the-art analytical equipment backed by our comprehensive local technical support and warranty services. The analyzer is engineered to provide online, real-time measurement of multiple gases simultaneously, achieving the shortest response times in the industry—often within mere seconds.
Measurement and Operating Principle
At the core of the Cubic LRGA-3100 lies the sophisticated principle of laser Raman scattering. When the internal laser beam interacts with the gas molecules within the sample chamber, a small fraction of the scattered light shifts in wavelength. This shift is highly specific to the molecular bonds of the respective gas. The Cubic LRGA-3100 precisely enhances, collects, processes, and identifies these characteristic Raman scattering spectra to determine exactly which gases are present.
Once the characteristic spectra are identified, the internal processing unit of the Cubic LRGA-3100 quantifies the exact content and concentration of each gas. Unlike traditional gas chromatography, this laser Raman methodology allows the Cubic LRGA-3100 to analyze different components using baseline-separated peaks, delivering chromatogram-like analysis without the significant operational delays. This advanced spectroscopic approach ensures that the Cubic LRGA-3100 delivers unparalleled analytical precision without requiring ongoing calibration.
Engineering Design of the Cubic LRGA-3100
The structural integrity of the Cubic LRGA-3100 is designed to meet the rigorous demands of heavy industry. By utilizing state-of-the-art miniaturized optical components, the analyzer boasts a highly compact footprint (L590 x W480 x H177 mm). This transportable design allows the Cubic LRGA-3100 to be easily integrated into existing plant infrastructure or deployed as a mobile diagnostic unit across various process lines.
Furthermore, the Cubic LRGA-3100 is engineered for extreme durability. When equipped with a proper gas conditioning system, the analyzer is fully capable of being mounted online in harsh process conditions characterized by high temperatures and high pressures. This robust construction ensures that the Cubic LRGA-3100 maintains continuous, reliable operation, effectively eliminating the frequent maintenance downtime associated with less durable analytical instruments.
