Overview
LRGA-3100 is a compact laser Raman gas analyzer derived from the LRGA-6000, identifying gases by their Raman fingerprint spectra and measuring many components simultaneously within seconds—including H2, N2 and O2. It calculates calorific value and Wobbe index in real time and needs no carrier gas or consumables.
Key Features
- Non-destructive analysis of gases like CO, CO2, CH4, C2H2, C2H4, C2H6, C3H8, H2O, H2S, NH3, iC4, nC4,etc. including homonuclear diatomics like H2, N2, O2.
- Real time calculation of gas quality indexes like Calorific value, Wobbe index, etc.
- Wide detection range from 0.1% to 100% with high resolution and accuracy.
- Fast response time in seconds, suitable for industrial online continuous monitoring.
- Strong anti-interference ability based on Laser Raman technology of gas characteristic fingerprint spectrum.
- No carrier gas required and no consumables, low operation cost.
- Capable of mounting online in harsh process conditions of high temperature and high pressure with proper gas conditioning system.
