Laser Raman Spectroscopy Gas Analyzer

Product Overview

The Laser Raman Spectroscopy Gas Analyzer is developed based on the principle of laser Raman scattering, enabling real-time, online qualitative and quantitative analysis of multi-component gases. Optimized optical paths and compact structural design make the instrument portable and suitable for both industrial field use and laboratory analysis. It can measure gases such as H₂, N₂, O₂, CO, CO₂, CH₄, and H₂S with a response time on the order of seconds, ensuring rapid and accurate measurements.

Technical Principles

The analyzer uses laser Raman scattering to capture and enhance the characteristic Raman spectra of gas molecules. By analyzing the gas-specific spectral fingerprints, it performs precise qualitative and quantitative measurements of multiple gas components. The entire process—from data acquisition to processing and display—is online and real-time, eliminating long waiting times.
