HCI / H2O Hydrogen Chloride Analyser - Trace Gas

LGR’s Hydrogen Chloride Analyser (HCl Analyser) continuously measures HCl in ambient air or in industrial process flows with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time to measure hydrogen chloride gas with high sensitivity – LGR’s Hydrogen Chloride Analyser provides measurements every second with ppb-level precision. In addition, the analyser can report measurements quickly over a very wide range of HCl mole fractions.

LGR’s HCl Analyser is available in two packaging options to allow users to select the configuration most suitable for their needs. LGR’s standard rackmount package fits in a 19” wide instrumentation rack and requires an external keyboard, mouse, and video monitor. For highest performance, the HCl Analyser is now available in LGR’s “Enhanced Performance” (or EP) package. The EP package incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy and drift. In addition, the HCl Analyser is now available in LGR’s “ultraportable” package which is compact, crushproof and is small enough to be carried on-board aircraft (TSA approved).

Features and Benefits

  • Fastest response: 1-Hz continuous measurements allow observation of transient and time varying flows
  • Measures a wide range of concentrations
  • High-resolution absorption spectra always viewable
  • Low power: ideal for field applications
  • New Enhanced Performance model provides ultra-low drift and unsurpassed precision

Please choose which specification you require information about

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.
