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.
