In this new article, Martin Schiller, Chad Paton and Martin Bizzarro of the Centre for Star and Planet Formation at the University of Copenhagen report a novel approach for the chemical purification of Ca from silicate rocks by ion-exchange chromatography, and a highly-precise method for the isotopic analysis of Ca by high-resolution multiple collector inductively coupled plasma source mass spectrometry (HR-MC-ICPMS), in combination with thermal ionization mass spectrometry (TIMS).
