Type: Laser Raman Gas Analyzer

Model No.:LRGA-6000

Laser Raman Spectrometer Gas Analyzer LRGA-6000 is 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. Online real time measurement for various gases on full range simultaneously.

• High precision with Laser Raman gas characteristics fingerprint technology.
• Full function to measure all the main components in synthesis gas in one instrument.
• Can online measure multi-components gas, including H2S, in real time.
• Wide detection range from 0.01 -100%, for full-range gas concentration measurement.
• Quick response, directly show all the composition after sample gas enter into analyzer.
• Low operation & maintenance cost, no carrier gas, no consumables.
• Automatic temperature and pressure correction, no drift in using.

Compare with infrared analysis technology – Most NDIR infrared gas analyzer can only detect a single component with small range. N2, O2, H2 cannot be detected as no infrared effect. LRGA-6000 has larger range, higher precision, and can detect more types of gas.
Compare with GC Gas Chromatography – GC requires carrier gas and chromatographic columns, and the response time usually takes several to tens of minutes, and requires for professional trained personnel to operate. LRGA-6000 responses very fast, requires no carrier gas and consumables, with easier operation and lower operation cost.
Compare with MS mass spectrometry – the mass spectrometer is very expensive, and with high maintenance costs and complicated operation, it is rarely used as an industrial field analyzer. With robust design, simple operation, low maintenance cost, LRGA-6000 is more suitable to be used in harsh industrial environment for online monitoring.
