LGR’s Isotopic Water Analyzer (model IWA-45EP) is the world’s most advanced instrument for measurements of both isotopic liquid water (including wines) and water vapor. The IWA-45EP combines the features of LGR’s Liquid Water Isotope Analyzer and Water Vapor Isotope Analyzer (Enhanced Performance model) in a single instrument. For liquid water samples, the IWA-45EP reports measurements at a rate of over 800 injections per day. With the typical operating procedure (6 injections per sample), this measurement rate yields over 130 total samples per day. For continuous measurements of water vapor, the IWA-45EP reports δ17O , δ18O and δ2H and water vapor mole fraction over a range of mole fractions greater than 60000 ppm H2O in air. Changing between operational modes could not be simpler - with only a simple switch, the user can switch from measuring liquid water to measuring water vapor, or vice versa.
EnquiryFor measurements of isotopes in wine, please refer to the description in LGR's Wine Isotope Analyzer.
The IWA models are part of LGR’s new “Enhanced Performance" series which incorporates proprietary internal thermal control for ultra-stable measurements with negligible drift, unsurpassed precision and highest accuracy.
The Analyzer uses LGR’s patented Off-axis ICOS technology, a fourth-generation cavity ringdown spectroscopy (CRDS) technique, which employs an optical cavity to greatly enhance spectral absorption and enable the fastest and highest precision measurements of any laser absorption technique. LGR’s patented technology has many proven advantages over conventional first-generation CRDS techniques. As a result, LGR analyzers are simple to build, inherently robust and easy to operate. As with all LGR analyzers, the IWA models provide users with measured high-resolution absorption spectra for comprehensive performance validation and diagnostics in real time. Similarly, the instrument has an internal computer (Linux OS) that can store data practically indefinitely on an internal hard disk drive and send real time data to a data logger via the digital (RS232) or Ethernet outputs. In addition, the Analyzer includes (at no extra cost) advanced Post-Analysis Software which provides many features that increase user productivity, decrease data processing time, and provide data and system diagnostics.
All LGR analyzers may be fully controlled remotely via the Internet. This capability allows users to operate the Analyzer using a web browser anywhere internet access is available. Furthermore, remote access provides the opportunity to obtain and share data and to diagnose the instrument operation without being on site.
