Abstract: The nickel isotope has a great potential for investigating biogeochemical processes in the geosciences and has been proven to be extremely useful for studying the chronology of the early solar system. As one of the most powerful techniques in metal isotopic ratio measurements, thermal ionization mass spectrometry (TIMS) shows poor sensitivity for Ni isotope ratio analysis, because the high ionization potential (7.640eV) of Ni makes it difficult to be ionized on a hot filament. In previous studies, a minimum of…
