Precise Zn-66/Zn-64 and Zn-68/Zn-64 isotopic ratios of biochemical samples have been measured using multiple collector-ICP-mass spectrometry (MC-ICPMS). In order to eliminate the mass spectrometric interferences on Zn isotopes (e.g., Ni-64+ and Ba...

Precise Fe-56/(54) Fe and Fe-57/Fe-54 isotopic ratios on human red blood cell (RBC) samples have been measured using multiple collector-ICP-mass spectrometry (MC-ICPMS). The mass spectrometric interferences on Fe isotopes (e.g., (ArO+)-Ar-56 and (...
A short course on inductively coupled plasma-mass spectrometry (ICP-MS) was held from 6th to 7th September, just before the Goldschmidt Conference at Kurashiki. This short course covered the entire range of ICP-MS techniques, including basic princ...

Iodine-131 distribution released from the Fukushima Dai-ichi Nuclear Power Plant accident was reconstructed through the iodine-129 measurements. From nearly 1,000 surface soil samples iodine was extracted by the pyro hydrolysis method. Extracted i...
