Lab "Stable Isotopes"

Joint venture between Goethe University and BIK-F

Head: Prof. apl. Dr. Jens Fiebig

The stable isotopic composition of geomaterials reveals important constraints on their origins, formation temperatures and alteration histories. Our laboratory is equipped with 2 MAT 253 gas source mass spectrometers, 1 MAT 253Plus gas source spectrometer, and gas preparation devices enabling the following routine analyses:

  • clumped isotope (Δ48 and Δ47) analysis of CO2 and carbonates
  • carbon and oxygen isotope analysis of carbonates
  • oxygen isotope analysis of silicates
  • H- and O-isotope analysis of waters
  • molecular-specific carbon isotope analysis of gaseous hydrocarbons
  • H-isotope analysis of OH-bearing silicates
  • C- and N-isotope analysis of bulk organic matter
  • S isotope analysis of S-bearing minerals
  • H-, C-, N-, O- and S isotope analysis of volcanic gases (H2O; CO2, CH4; N2, H2)
