The Neptune* in the Isotope Geochemistry and Geochronology Research Center (IGGRC) is up and running!

*Recently, the IGGRC added a Thermo-Finnigan NEPTUNE© multicollector inductively coupled-plasma-mass spectrometer (MC-ICP-MS) to their laboratory facilities. The MC-ICP-MS uses an argon-based plasma to ionize elemental species allowing the instrument to analyze a wide range of isotopes (6Li to 238U), including those elements TIMS cannot ionize (e.g., Hf). The recently acquired NEPTUNE© therefore dramatically expands the capabilities of the IGGRC.
