CH4 / C2H6 Methane & Ethane Analyser - Trace Gas

LGR’s new Fast Methane/Ethane Analyser (FMEA) reports measurements of methane and ethane, the two major components of natural gas, simultaneously.

LGR’s patented technology, a fourth-generation cavity-enhanced absorption technique, has many advantages (simpler, easier to build, rugged) over older, conventional cavity ringdown spectroscopy (CRDS) and direct absorption techniques. As a result, LGR Analysers provide higher performance and reliability at lower cost.

Available as Rackmount/Trace Gas or Ultraportable.

Features and Benefits

  • 15 kg, 70 watts, portable
  • Data collection within 2 minutes after power on
  • Data reported at 5 Hz
    Gases measured simultaneously
  • All spectra always viewable
  • CH4 and C2H6 reported directly
  • Ideal for natural gas leak detection and compliance monitoring
  • Wide measurement range
  • Species specific - no cross interferences
  • Operates directly on DC power

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.
