Deep Water Gas Analyser

Deep Water Gas Analyser

The Deep Water Gas Analyser combines membrane separation technology with Los Gatos Research’s cavity enhanced laser absorption spectroscopy technology to provide in situ measurements of methane and carbon dioxide at depths to 2500 meters.

Designed for applications such as ocean acidification, carbon sequestration, methane hydrate and hydrothermal vent studies, these novel analysers provide real-time measurements of dissolved gases in oceans and lakes. The analyser is designed to be lowered to the desired depth or carried by submarine. Power is supplied from the surface via cable.

The analyser includes an internal computer that can store data practically indefinitely on its internal hard drive and can be read from the instrument in real time during operation through a connecting cable. Power and interface cables are not included with analyser.

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.
