CO, CO2, H2O, O2 Industrial Emissions Analyser

LGR’s new Industrial Emissions Analyser (CO, CO2, H2O, O2), or IEA, is the first laser-based instrument capable of simultaneous measurements of carbon monoxide, carbon dioxide, water vapor and oxygen. The IEA is simple to use, sensitive, and rugged which makes it ideal for continuous emissions monitoring, industrial process control and compliance monitoring applications. In addition, the IEA is now available in LGR’s “ultraportable” package which is  compact, crushproof and travels anywhere. Small enough to be carried on-board aircraft (TSA approved), the IEA offers opportunities to measure target gases anywhere. The IEA ultrafast  response provides users with real-time data and the opportunity for closed-loop feedback  control for continuous online optimization of processes such as furnaces (steel, glass  manufacturing), incinerators, chemical production plants, petrochemical refineries and other high temperature processes.

  • All gases measured simultaneously
  • Gases reported on dry mole basis directly
  • High resolution absorption spectra always viewable
  • Ideal for process and compliance monitoring
  • Wide measurement range
  • Unsurpassed sensitivity and accuracy
  • Simple maintenence

Please choose which specification you require information about

All LGR Analysers now come with a 2 Year Warranty as standard, underlying the quality and robustness of their manufacture and high reliability. Warranties can also be extended to 3 or 4 years at additional cost, at the time of purchase. Please enquire for further details.

Under normal operation and for the vast majority of applications, LGR Off-axis ICOS gas analysers require the minimum of servicing and maintenance.

One of the many benefits of this technology is long-term unattended reliability in the field.

LGR Advantages

Annual maintenance would normally include an inspection of the internal pump (or external pump if fitted) and the replacement of the pump diaphragm and valve seals if necessary.

This can be carried out by the user themselves or by ET either on site or back in the ET workshop (for a maintenance quote, please contact us).

ET recommends that LGR Analyser users consider the purchase of a field maintenance kit which includes:

  • Replacement solid-state hard-drive with LGR operating system and specific system files pre-loaded, for quick and simple swap-out in the field if ever necessary.
  • Pump maintenance kit (internal) to include spare pump diaphragm and valve seals.
  • Mirror cleaning kit.


Please contact us if you would like to receive a quote for the field maintenance kit.

Additional maintenance will be required for the LGR Liquid Water Isotope Analyser (LWIA) and Auto-injector unit and also the LGR Dissolved Gas Extraction Unit (DGEU).

For these instruments, please refer to the operation manual supplied with these instruments.
