ABB LGR-ICOS Enhanced performance rackmount gas analyser GLA331
Sensitive ammonia measurements in seconds Absolutely Ammonia Analyzer (NH 3 , H 2 O) Features and Benefits • 1-Hz measurements: allow observation of transient and time varying flows • Accurate measurements over a wide range of concentrations • High resolution absorption spectra viewable for diagnostics • Reports ammonia and water vapor simultaneously • Reports water vapor up to 60,000 ppm • Low power: ideal for field work • Enhanced Performance model provides lowest drift and highest accuracy • Reports ammonia in ethylene flows (optional) LGR’s Ammonia Analyzer provides sensitive measurements of ammonia (and water vapor) 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 ammonia with high sensitivity – LGR’s Ammonia Analyzer provides measurements every second with ppb-level precision. In addition, it can report measurements quickly over a wide range of concentrations. LGR’s new “Enhanced Performance series” incorporates proprietary internal thermal control for ultra-stable, minimal-drift measurements with unsurpassed precision and accuracy. The AA is available in different packaging options to allow users to select the one most suitable for their needs. LGR’s benchtop package includes a keyboard, mouse, and video monitor. LGR’s rackmount package fits in a standard instrumentation rack and requires an external keyboard, mouse, and video monitor. The Ammonia Analyzer is now available in the new Ultraportable package (called the UAA), which is compact, crushproof and travels anywhere. Small enough to be carried onboard aircraft (TSA approved size) and requiring only 60 watts (on battery power), the AAultraportable offers opportunities to measure NH 3 anywhere. For details, see UAA datasheet. The AA and UAA use 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 techniques such as being alignment insensitive, having a much shorter measurement time, and not requiring expensive auxiliary components. All LGR instruments include an internal computer (Linux OS) that can store data practically indefinitely on its internal hard drive (for unattended long-term operation), and that can send real-time data to a data logger through its analog, digital (RS232) and Ethernet outputs. Furthermore, the instruments may be controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser anywhere Internet access is available. Furthermore, remote access allows the opportunity to control, obtain data from, and diagnose, the instrument without being on site.
