Stable Isotope Laboratory

Analyses Available: 

  • Isotopic analyses of hydrogen (1H/2H), carbon (13C/12C), nitrogen (15N/14N), and oxygen (18O/16O)
  • δ13C and δ18O of solid inorganic samples such as carbonate material
  • δ13C and δ15N of solid inorganic (such as soils) and organic (such as plant or animal material) by combustion
  • δ2H and δ18O of solid inorganic (such as soils)  and organic (such as plant or animal material) by pyrolysis
  • δ2H and δ18O in water
  • δ13C of dissolved inorganic carbon (DIC) in water 

Finnigan MAT 252

Kiel III Carbonate Device

The Kiel III Carbonate Device coupled to a Finnigan MAT 252 Isotope Ratio Mass Spectrometer (IRMS) allows for high-precision, high-throughput analysis of carbonate samples following acid digestion.

  • δ13C and δ18O of solid inorganic samples

 Dual Inlet

The Dual-Inlet system of the Finnigan MAT 252 IRMS allows for the highest precision analysis of pure gas samples following offline preparation.
