Product Name: Isotopic Water Analyzer (δ2H, δ17O, δ18O, d-excess, 17O-excess)
上市Date:2019-05-06

4 isotopologues, 3 isotopic ratios, 2 phases, 1 instrument

Features and Benefits: 

• Comprehensive system provides unparalleled performance for both isotopic liquid water and water vapor measurements

• Reports δ2H, δ17O, δ18O, d-excess, 17O-excess (and H2O in vapor mode) in real time

• High Throughput and High Performance modes in 1 system

• Switch between liquid and vapor measurements in seconds

• Highest accuracy water vapor

• Isotopic water vapor reported at high and low mole fractions

• Fast time response allows isotopic water vapor flux studies

• Enhanced Performance series provides unsurpassed stability and lowest drift

• Low power: 180 W (steady state)

• Widest temperature range: 0 - 45 °C (EP model)
