Innovations in Isotope Mass Spectrometry and Isotope Metrology in Geosciences Posters


Submit an Abstract to this Session


Session ID#: 44491

Session Description:
Isotope mass spectrometry is essential to geochemical research, and recent advances in solution and in-situ technologies and methodologies of AMS, TIMS, MC-ICPMS, SIMS, Noble Gas MS, High Res IR MS, and others have spawned new applications in diverse fields of earth sciences. We invite contributions that emphasize new developments in isotope mass spectrometry, including advances in instrumentation, establishment of isotope reference materials, techniques for high precision ratio determinations, and methods for measuring radiogenic, cosmogenic, and stable isotopes, among others.
