Water Vapor Isotope Analyzer (H2O, δ2H, δ17O, δ18O)

Now you can accurately measure δ17O, δ18O and δ2H in ambient water vapor (to over 60,000 ppm) rapidly with high precision in a measurement time of less than 0.5 seconds. Our Water Vapor Isotope Analyzer requires only 180 watts of power and does not require any sample preparation or user intervention, which enables long-term studies of water-vapor isotopes with unprecedented performance. In addition, the  Water Vapor Isotope Analyzer provides simultaneous measurements of water vapor mole fraction [H2O] with ppm-level precision. For measurements of liquid water as well as water vapor in one instrument, please refer to LGR's new Isotopic Water Analyzer.

LGR's  Water Vapor Isotope Analyzer works seamlessly with LGR's Water Vapor Isotope Standard Source (WVISS), which provides a controllable flow of humid air with known isotope values for  δ17O, δ18O and δ2H over a continuous range of H2O mole fractions (not just at a couple of concentrations).  The  Water Vapor Isotope Standard Source automatically and comprehensively characterizes the operation of the Water Vapor Isotope Analyzer (WVIA) in real time and without user intervention. Together, the WVIA and WVISS provide reliable, real-time, dual-inlet, absolute measurements of δ17O, δ18O and δ2H in ambient water vapor - no other combination provides comparable accuracy, precision and dynamic range.  The rugged, field-portable packaging makes this instrument ideally suited for a myriad of hydrological, atmospheric science, medical, and industrial monitoring applications.
