H2S/NH3 Analyzer (Hydrogen Sulfide, Ammonia, Water Vapor)

H2SNH3 Analyzer

LGR’s H2S/NH3 Analyzer (ammonia, hydrogen sulfide) provides sensitive measurements in ambient air or in industrial process flows with extremely high precision and sensitivity. No longer do you have to wait a long time to measure these gases with high sensitivity and accuracy – LGR’s H2S/NH3 Analyzer provides measurements every second with sub-ppm level precision. In addition, the H2S/NH3 Analyzer can report measurements quickly over a very wide range of mole fractions even in complex process flows.

LGR’s H2S/NH3 Analyzer is available in different versions to allow users to select the model suitable for their needs. LGR’s “high sensitivity” model is designed for ultra trace detection of NH3 and H2S in ambient air, industrial process streams, or wherever highest detectivity is required.  LGR’s “industrial” model is designed for high accuracy measurements in complex processes which contain NH3 and H2S at levels that exceed the dynamic range of other analytical techniques. 

LGR’s new “Enhanced Performance” series incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy and drift.  LGR’s new “Ultraportable” series provides unparalleled ease of transport for users to hand carry the instrument (15 kg, 60 watts) anywhere. 

The H2S/NH3 Analyzer uses LGR’s patented Off-axis ICOS technology, a fourth-generation cavity enhanced absorption technique. Off-axis ICOS has many advantages over conventional cavity ringdown spectroscopy (CRDS) techniques such as being alignment insensitive, having a much shorter measurement time, and not requiring expensive and complicated components.

LGR Analyzers include an internal computer (Linux OS) that can store data practically indefinitely on an internal hard drive (for unattended long-term operation), and send real-time data to a data logger through its analog, digital and Ethernet outputs.

Furthermore, LGR instruments may be fully controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser anywhere Internet access is available. Remote access allows full control of the instrument and the opportunity to obtain data and to diagnose the instrument operation without being on site.
