Dating techniques and its application by Accelerator Mass Spectrometry; Improvement in preparation method for ultra-trace analysis

Watanabe, Takahiro

Accelerator Mass Spectrometry is widely used for radiometric dating of geological samples. Radiocarbon, Beryllium-10 and Aluminum-26 measurements by Accelerator Mass Spectrometry have been developed at the Toki Research Institute of Isotope Geology and Geochronology, Tono Geoscience Center, JAEA. However, improvement in efficiency of sample preparation techniques and ultra-trace analysis are needed for high-time resolution dataset. In this study, we improved preparation method for radiocarbon dating using elemental analyzer (EA) and automated graphitization equipment (AGE3).
