In-Situ Laser Raman Gas Analyzer

Product Overview

The In-Situ Laser Raman Gas Analyzer is a high-performance gas analysis instrument based on laser Raman scattering. Utilizing enhanced spectral features, it provides both qualitative and quantitative analysis of multiple gas components.

The system supports in-situ installation and comes with a dedicated Raman sampling probe, enabling continuous, online, and non-destructive monitoring of gases directly in industrial processes. With a response time on the order of seconds, it can simultaneously monitor up to 20 gas components. The analyzer also features positive-pressure explosion-proof design, ensuring safe operation in hazardous environments.

Working Principle

The analyzer operates on the Raman scattering principle, where laser light interacts with gas molecules, generating characteristic Raman spectra. The system enhances, collects, and processes these spectral signals to achieve high-precision qualitative and quantitative analysis of multiple gas components.

The in-situ Raman probe measures gases directly on-site, eliminating the need for gas extraction or pre-treatment, minimizing sample loss and measurement delays, and improving efficiency and reliability.

Key Features

• High-Precision, Non-Destructive Analysis: Supports accurate measurement of diatomic molecules such as H₂, N₂, O₂, and other gas components.
• Multi-Component Continuous Monitoring: Simultaneously monitors up to 20 gas species, suitable for complex industrial processes.
• In-Situ Measurement Design: Raman probe directly measures gases at the process site, reducing maintenance and operational complexity.
