Accurate CO and CO2 Analysis in Gas Streams

Accurate measurement of carbon monoxide and carbon dioxide is essential in petrochemical, hydrogen and industrial gas applications. Even trace levels of CO and CO2 can impact product quality, catalyst performance and process efficiency. Reliable and sensitive analysis is therefore critical for both process control and product certification.

The GAS CO-CO2 Analyser provides a robust and highly reliable GC solution for the determination of CO, CO2 and methane in a wide range of gas matrices, including hydrogen and hydrocarbon streams. Based on methaniser-FID technology, the analyser converts CO and CO2 into methane for sensitive detection, enabling sub-ppm analysis with detection limits down to 50 ppb. The system is fully compliant with UOP 603-13 and designed for long term stability and high uptime.

Applications

  • Petrochemical Process Monitoring
    Analyse CO and CO2 in ethylene, propylene and other hydrocarbon streams.
  • Hydrogen Purity Analysis
    Detect trace levels of CO and CO2 in hydrogen for fuel cell and industrial applications.
  • Industrial Gas Quality Control
    Verify gas composition and impurity levels in industrial gas production and distribution.
  • Catalyst Protection and Process Control
    Monitor impurities that can affect catalyst performance and process efficiency.
  • Laboratory and On-Line Analysis
    Suitable for both laboratory testing and continuous process monitoring.

Benefits

  • UOP 603-13 Compliance
    Fully aligned with industry standard method for CO and CO2 analysis.
  • High Sensitivity
    Detection limits down to 50 ppb for CO, CO2 and methane.
  • Robust Valve Technology
    Diaphragm valves with internal purge offer long lifetime and reduced maintenance.
  • Reliable Methaniser-FID Detection
    Accurate and selective detection of CO and CO2 via conversion to methane.
  • Flexible Configuration
    Available on both benchtop GC and CompactGC platforms with multiple options.
