NH3 / O2 / H2O Ammonia / Oxygen Analyser - Trace Gas

Los Gatos Research's new Ammonia/Oxygen Analyser provides sensitive measurements of ammonia and oxygen in ambient air or in process flows (MOCVD) with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time or rely on scrubbers to measure ammonia, oxygen and water vapour with very high sensitivity – LGR’s Ammonia/Oxygen Analyser provides direct measurements every second with extremely high precision.

In addition, the Ammonia/Oxygen Analyser can report measurements quickly (fast response time) over a very wide range of concentrations. The instrument, based on LGR’s cavity enhanced laser absorption spectroscopy, is simple to use, inexpensive to operate, and includes all components (internal vacuum pump, keyboard, mouse, video monitor) to start recording data within minutes.

The Analyser has an internal computer (Linux OS) that can store data practically indefinitely on its hard disk drive and send real time data to a data logger via the digital (RS232) or Ethernet outputs.  Furthermore, as with all LGR analysers, this Analyser may be controlled remotely via the Internet. This capability allows the user to operate the analyser using a web browser practically anywhere Internet access is available. This remote access allows the opportunity to obtain data and to diagnose the instrument operation without being on site.

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.
