ABB’s Tripe Isotopic Water Analyzer, GLA431-TIWA, is the only instrument for isotopic water measurements (liquid water and water vapor) capable of reporting all major isotopologues (H2O, H2HO, H217O, H218O) simultaneously. The IWA combines the features of ABB’s Triple Liquid Water Isotope Analyzer (GLA431-TLWIA) and Water Vapor Isotope Analyzer (GLA331-TWVIA) in a single instrument. Changing between operational modes could not be simpler. With a simple toggle switch, the user can quickly change from measuring liquid water to water vapor, or vice versa.
