CH4 Fast Methane Analyser - Trace Gas
The Los Gatos Research (LGR) Fast Methane Analyser (FMA) provides extremely precise (0.1 ppbv) measurements of methane (CH4) at up to 20 Hz. In addition to accurately monitoring typical ambient methane levels, the unprecedented response of LGR’s FMA allows measurements at very high mixing ratios (up to 1000 ppmv) for applications including landfills, peatlands and chamber flux studies. The FMA is simple to use, low power, and rugged which makes it ideal for field studies that involve measurements of this key greenhouse gas.
Features and Benefits
- Measure methane at up to 20 Hz
- High resolution absorption spectra are viewable for diagnostics
- Requires only 80 watts (with internal pump)
- Measurements over extremely wide range (up to 1000 ppmv)
- Eddy covariance flux measurements
- Chamber studies
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.
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.
