Frequently Asked Questions

Common questions about our analytical instruments

Paramagnetic oxygen analyzers measure oxygen based on its magnetic susceptibility and are ideal for high-purity applications (0-1000 ppm or 0-25%). They offer excellent accuracy and stability. Zirconia oxygen analyzers use a ceramic sensor that generates a voltage proportional to oxygen concentration and are better for high-temperature applications or wider ranges (0.1 ppm to 100%). Paramagnetic analyzers are preferred for inert gas purity measurement, while zirconia analyzers are commonly used in combustion control and high-temperature processes.

Calibration frequency depends on the analyzer type, application, and required accuracy. For critical process control applications, calibration should be performed monthly or quarterly. For less critical applications, semi-annual or annual calibration may be sufficient. Most analyzers feature automatic calibration routines using certified calibration gases. We recommend:
  • Oxygen analyzers: Every 1-3 months
  • Dew point meters: Every 3-6 months
  • Hydrocarbon analyzers: Every 1-2 months
  • Multi-gas analyzers: Monthly calibration for critical components

Proper sample conditioning is essential for accurate analysis. Typical conditioning includes:
  • Particulate filtration: Remove particles >0.1-1 micron to protect analyzers
  • Moisture removal: Refrigerative or desiccant drying for moisture-sensitive analyzers
  • Pressure regulation: Maintain constant pressure to analyzer
  • Temperature control: Heating for wet gases, cooling for hot gases
  • Flow control: Constant sample flow rate
  • Chemical scrubbing: Remove interfering gases if necessary
Our sampling systems include appropriate conditioning based on your specific application requirements.
