In the H2-H2O equilibration method for D/H measurement of water samples, an improved handling of Pt catalyst was proposed. The catalyst was wrapped in a Teflon® filter to prevent dispersion of fine fragments of the catalyst. Despite a reduced rate of isotope exchange reaction, equilibrium was attained within 24 h at 25°C. A conventional unit for automatic CO2-H2O isotope exchange reaction can be used for this purpose.
