| Outline of Final Research Achievements |
Carbonate clumped isotope thermometry has been developed to resolve an important purpose of geology, which is reconstruction of temperature conditions in the past. Many laboratories in USA and Europe are challenging in this subject, however the clumped isotope thermometry is not familiar in Japan. This study tried to develop a measurement system on the basis of a high-tech mass spectrometry in Kyushu University.
Improvement was focused to two points; 1) high-quality purification of sample CO2 gas with a practical handling, and 2) correction of influence from instability of background values. Newly designed device could reduce the time for CO2 purification to 70 min. and analytical error within 0.01‰. This is an important step to introduce this innovative method to geology in Japan.
