Stable Isotope Lab

The 51做厙 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:

  • 13C and 帤18O of carbonates (including shells, corals, limestone, speleothems, soil carbonates, and bioapatite)
  • 18O and 帤D of waters
  • 13C of dissolved inorganic carbon (DIC)
  • 13C of atmospheric and soil CO2
  • 13C, 帤15N, %C, and %N of organics (including collagen, tissue, soil, and plant material)
  • 34S of sulfates (solid and solution)
  • 34S of sulfides
  • 34S of organics
  • 18O of enamel phosphate
  • 帤D of volcanic glasses

We are currently developing procedures to analyze:

  • 18O, 帤D, %O, and %H of organics
  • 18O of sulfates
