The aim is to measure calcium isotope ratios using advanced mass spectrometry techniques.
Conducted continuous flow analyses with the Neoma MC-ICPMS/MS
Utilized H2 or SF6 as ionization gases
Performed approximately 1,000 Ca isotope ratio measurements
Achieved high precision in calcium isotope ratio measurements
Demonstrated the effectiveness of the continuous flow sample introduction system
Abstract
This paper reports Ca isotope ratio measurements (n ~ 1,000) from May 2024 to October 2025 using the Neoma MC-ICPMS/MS equipped with a continuous flow sample introduction system (microFAST Isotope...
