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.
