The University of South Florida Stable Isotope Lab (USFSIL) provides stable C, H, O, N, and S isotope analyses of both organic and inorganic samples to researchers from geology, anthropology, biology, geography, and more.  We commonly analyze:

  • δ13C and δ18O of carbonates (including shells, corals, limestone, speleothems, soil carbonates, and bioapatite)
  • δ18O and δD of waters
  • δ13C of dissolved inorganic carbon (DIC)
  • δ13C of atmospheric and soil CO2
  • δ13C, δ15N, %C, and %N of organics (including collagen, tissue, soil, and plant material)
  • δ34S of sulfates (solid and solution)
  • δ34S of sulfides
  • δ34S of organics
  • δ18O of enamel phosphate
  • δD of volcanic glasses

 

We are currently developing procedures to analyze:

  • δ18O, δD, %O, and %H of organics
  • δ18O of sulfates
