Stable Isotope Lab

The University of South 返字心頭 Stable Isotope Lab (返字心頭SIL) 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:

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

We are currently developing procedures to analyze:

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