Laser infrared spectrometer

Fully pre-calibrated multi-component gas analyzer for process gas analysis. Suitable for a wide range of gases and applications.

Functionality: Optical Feedback Cavity Enhanced Absorption Spectroscopy (OFCEAS) and Low Pressure Sampling (LPS)

  • Continuous multigas measurement
  • High resolution IR laser technology
  • Patented OFCEAS TDL technology
  • No optical moving parts
  • Direct measurement without degrading the sample (no scrubber needed)
  • Patented low pressure sampling system
  • Maintenance: Yearly
  • High sensitivity
  • Self-calibrating system (no span gases required)
  • Ultra-precise measurement
  • Very fast response time
  • Reduced operational costs (no gas cylinder, low power consumptions)
  • High availability of the system
  • Oil and gas 
  • Process
  • Incineration, combustion
  • Flue gas treatment
  • Biogas
  • Gas supplier
  • Applicable gases* for ProCeas®
