This paper describes advances in isotopic measurements that have been made with an inductively coupled plasma source magnetic sector multiple collector mass spectrometer (MC-ICP-MS) and presents results of new experiments aimed at further evaluating the instrumental capability as well as the correction technique for the mass discrimination effects. The ability to correct for the mass discrimination effect using a second element of similar mass and very high sensitivity for elements that are otherwise difficult to ionize gives this instrument major advantages over other conventional techniques for isotopic measurements. The isotopic data obtained by MC-ICP-MS clearly demonstrate potential as a new technique to produce precise and reproducible isotopic data for the elements that are difficult to measure by thermal ionization mass spectrometry (TIMS).
