A method combined oxidation catalyst and water bubblers has been used as one of the most quantitative analysis methods for gaseous tritium. We previously developed a quantitative analysis system to measure gaseous tritium in a high accuracy using by an organic-based hydrophobic platinum catalyst. However, the previous tritium analysis system has a shortcoming that the organic-based catalyst has no resistance to a high temperature of more than 100oC, so that the system was not able to measure combustible gas such as tritiated hydrocarbons because the heat of reaction of hydrocarbons combustion on catalyst was large. Then, we developed a hydrophobic platinum catalyst having heat resisting property and high activity to measure various chemical forms of tritium. A new quantitative analysis system using by the hydrophobic catalyst enhanced the thermal durability performed as good as the previous system over wide temperature range. The developed tritium measurement system is applicable widely for various tritium measurements., 29th Symposium on Fusion Technology}, title = {Improvement of Quantitative Analysis Method of Tritium Using Hydrophobic Catalyst}, year = {2016} }
