Trace Detection of Carbon Monoxide

The trace detection of CO allows for fast & continuous real-time measurements, eliminating batch processing techniques commonly found with GCs and also eliminates the need for regular calibration and provides the most sensitive CO measurement with the lowest operating cost. Improved detection limits for carbon monoxide (CO) make this analyzer a compelling solution for various applications as listed below:

  • UHP Gas Quality Control
  • Industrial Gas QC
  • Certified Reference Materials and Calibration Gases
  • Research and Development
  • Gas Standards Preparation
  • Quality Control for Process Gas or Bulk Gas Systems
  • Air Separation Units
  • Truck Fill Measurements
  • Fuel-cell Hydrogen Analysis – ASU Process Control
  • Syngas and Fuel gas
