The Light Stable Isotope Mass Spec Lab in the Department of Geological Sciences at the University of Florida provides isotopic and elemental analysis on a large number of materials. We analyze samples for scientists and students from a variety of departments at the University of Florida in addition to many US and international universities and institutions.
