Stable Isotope Laboratory

The Stable Isotope Lab at the University of Arkansas houses advanced instrumentation for isotope analyses.  Key instrumentation includes 3 isotope ratio mass spectrometers, capable of solid  carbon, nitrogen, sulfur, oxygen and hydrogen measurements.  Liquid sample for hydrogen, oxygen dissolve carbon and nitrate can also be measured.  Raw carbon dioxide and evolved CO2, carbonates are possible.  Other instrumentation includes a GC/MS and GC/FID for compound identification and quantification, an HPLC equipped with a charged aerosol detector  and a TOC/TN analyzer for dissolved carbon and nitrogen.  The facility has significant sample preparation equipment and space, fume hoods, ovens, lyophilizer and grinders.
