Outline of Final Research Achievements

A nobel micro-fluorination method has been developed for rapid high precision quadruple sulfur isotope analysis (Ueno et al., 2015 Chemical Geology). In contrast to the previous F2 method, reaction with solid CoF3 reagent allows us to fluorinate sulfide samples into SF6 gas within several second. Futhermore, the analytical protocols were successfully optimized for analyzing small samples down to 100 nmolS with the highest precision that has made by conventional F2 method. In addition, the same technique was shown to be applicable to fluorinate pyrites directly.
