The Stable Isotope Laboratory at Florida State University, which is located in the National High Magnetic Field Laboratory, has vacuum lines and a new state-of-the-art stable isotope ratio mass spectrometer (Finnigan MAT delta PLUS XP) with several peripheral instruments including a Finnigan MAT TC/EA (high-temperature conversion elemental analyzer) with zero-blank autosampler, a Finnigan MAT Gas Bench with CombiPAL autosampler and equilibration modules, a ThermoFinnigan Trace GC with GC/C and GC/TC interface, and a Carlo Erba Elemental Analyzer. The various peripheral instruments are interfaced with the stable isotope ratio mass spectrometer and enable a broad range of sample analyses:

  • Analysis of oxygen isotopes in inorganic samples such as phosphate, nitrate and sulfate.
  • Analyses of of bulk organic samples.
  • Analyses of oxygen and hydrogen isotopes in water samples.
  • Analyses of carbon and oxygen isotopes in carbonates, DIC and carbon dioxide.
  • Compound-specific isotopic analyses of carbon, nitrogen, and hydrogen in organic liquid or gas mixtures.
  • Chemical and isotopic analyses of bulk carbon and nitrogen in organic samples
Mass Spectometer

The mass spectrometer system was purchased with funds provided by a grant from the NSF Earth Sciences Instrumentation and Facilities program and the Florida State University. For more information, contact Dr. Yang Wang (, 850-644-1121).
