PRODUCTION OF HYDROGEN GAS AND ANALYSIS OF HYDROGEN ISOTOPE

PURPOSE:To achieve complete gasification of hydrogen contained in water by reduction in the production of hydrogen gas as a specimen for the determination of deuterium concentration of water for the analysis of hydrogen isotope ratio. CONSTITUTION:Water is reduced by reacting with metallic zinc gran...

Zusammenfassung:	PURPOSE:To achieve complete gasification of hydrogen contained in water by reduction in the production of hydrogen gas as a specimen for the determination of deuterium concentration of water for the analysis of hydrogen isotope ratio. CONSTITUTION:Water is reduced by reacting with metallic zinc granule 2 in a reaction tube 1 at a high temperature in vacuum to generate hydrogen gas. Metallic zinc granule 2 having a nickel concentration of >=10ppm is used as the zinc to be used in the above reaction.
