Outline of Final Research Achievements |
We have developed method measuring triple oxygen isotope ratios in sulfate, and this method enable us to analyze only 23 min/sample. We also reduce sample amount for multiple sulfur isotope analysis, and thus, we have now ready to measure both oxygen and sulfur mass-independent fractionation (MIF) in sulfate samples.
