PLGA-1000
Process Laser Gas Analyzer
The PLGA-1000 Process Laser Gas Analyzer is designed to measure hydrocarbons and other gases contained in process gases at petrochemical plants. It uses proprietary IRLAM™ technology to continuously measure low concentrations of acetylene (C2H2) and carbon dioxide (CO2) as impurities in high‑concentration methane (CH4) and ethane (C2H6), delivering high‑speed, high‑sensitivity performance.
Why Choose PLGA-1000
- Unmatched speed and sensitivity with proprietary IRLAM™ technology.
- Significantly reduces operational costs and maintenance.
- The use of a small gas cell (Herriot cell), etc. reduces the footprint of the analyzer and contributes to save your space.
- Directly replaces slower process gas chromatographs.
- Provides continuous, real-time data for immediate process adjustments, improving productivity and product quality.
- Expert-engineered solutions for specific applications.
