NO2 (Model NOOA-13d) Nitrogen Dioxide Analyser

LGR’s NO2 Analyser (model NOOA-13) uses cavity enhanced laser absorption spectroscopy to measure the mole fraction of nitrogen dioxide continuously and directly in flowing air samples. The Nitrogen Dioxide Analyser is ideal for a wide variety of monitoring applications of this gas where extreme precision, accuracy and fast response are required.

The NO2 Analyser’s ease-of-use and durability make it an ideal choice for field, flight and laboratory-based applications. LGR’s analysers are used by researchers, scientists, governmental agencies and intergovernmental organizations on all 7 continents.

  • High precision:
    0.05 ppb (1σ, 1 second)
  • Fast: data reported at 5 Hz
  • Low power: only 100 watts
  • Rugged: Proven in the field, in
    flight, and in the lab
  • No zero gas required:
    automatic chemical zero
  • Simple to use
  • Linear over wide range

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.
