Los Gatos Research's (LGR's) Ammonia Analyzer provides sensitive measurements of ammonia in ambient air or in process flows containing ethylene with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time or rely on scrubbers to measure ammonia with high sensitivity – LGR’s Ammonia Analyzer provides direct measurements every second with ppb-level precision. In addition, the Ammonia Analyzer can report measurements quickly (fast response time) over a very wide range of concentrations. The instrument, based on LGR’s cavity enhanced laser absorption spectroscopy, is simple to use, inexpensive to operate, and includes all components (internal vacuum pump, keyboard,mouse, video monitor) to start recording data within minutes.
The Analyzer has an internal computer (Linux OS) that can store data practically indefinitely on its hard disk drive and send real time data to a data logger via the digital (RS232) or Ethernet outputs. Furthermore, as with all LGR analyzers, this Analyzer may be controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser practically anywhere Internet access is available. This remote access allows bios-level control of the instrument and provides the opportunity to obtain data and to diagnose the instrument operation without being on site.
EnquiryThe analyzer uses LGR’s patented Off-axis ICOS technology, the fourth-generation cavity enhanced absorption technique, which employs a high-finesse optical cavity as the measurement cell. LGR’s technology has many proven advantages over conventional first-generation cavity ringdown spectroscopy (CRDS) techniques. In brief, since the laser beam does not have to be resonantly coupled to the measurement cell (i.e. precise beam alignment is not critical), LGR Analyzers are relatively inexpensive, simple to build, and inherently robust thermally and mechanically. In addition, since LGR’s technology can record reliable absorption spectra over a far wider range of optical depths (absorbance values) compared with CRDS, LGR Analyzers provide measurements over a much wider range of mole fractions (concentrations). Finally, due to the ease and simplicity of recording and quantifying the measured spectra using LGR’s Off-Axis ICOS, LGR Analyzers display the entire absorption spectra to the user in real time allowing for immediate system diagnostics and performance validation.
LGR’s new “Enhanced Performance series” incorporates proprietary internal thermal control for ultra-stable, minimal-drift measurements with unsurpassed precision and accuracy. For users wishing maximum portability, LGR’s new “Ultraportable” series provides unparalleled ease of transport for users to carry the instrument anywhere.
In brief, LGR’s Ammonia Analyzer provides the high quality data necessary for the most demanding applications including semiconductor process monitoring and atmospheric trace gas monitoring. Moreover, only LGR’s analyzers provide reliable measurements (with guaranteed specs) at extremely high concentrations (to 10 ppm ammonia in air). In addiiton, with optional ethylene capability, the instrument can report measurements of ammonia directly in 'pure' ethylene flows (without the need for any scrubber or background subtraction).
The 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 power consuming auxiliary components.
