Enhanced Performance Ammonia Analyser

NH3 Analyser (Enhanced Performance Rackmount) GLA331-EAA

As with all LGR-ICOS analysers, the GLA331-EAA is simple to use and offers a very wide dynamic range up to more than 100 times typical ambient levels. It is extremely rugged which makes it ideal for long-term monitoring or very low levels requiring extra stability.

The GLA331-EAA reports measurements of ammonia and water vapor simultaneously in an enhanced performance (EP) rackmount optimized for precision, accuracy and long-term stability.

Features and benefits

• Simultaneous measurements of NH3 and H2O

• Measurement rates selectable up to 10 Hz

• Extremely wide dynamic/linear range

• Highly specific: robust to cross-interferences

• State-of-the-art stability and precision

• Lowest drift

• Fast response time option

• Installed and operational in minutes

• Unsurpassed reliability

• Real-time diagnostics

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.
