Scope of the former IBG

What the IBG did:

• Abundance analysis of stable isotopes (δD, δ¹³C, δ¹⁵N, δ¹⁸O) for the BayCEER members
• Development of advanced analytical techniques for the abundance analysis of stable isotopes together with the scientific units of BayCEER
• Advising scientific institutions on planning and conducting experiments with stable isotopes in the natural abundance range and on their use as tracers.
• Own research projects using stable isotope abundance analysis
• Teaching courses on stable isotope applications in biogeochemistry using the available equipment

Which services it provided:

• Simultaneous determination of C and N isotope abundances (δ¹³C, δ¹⁵N) in the natural abundance range and of C and N concentrations in organic and inorganic solid samples using an EA-IRMS coupling.
• Simultaneous determination of H/D and O isotope abundances (δD, δ¹⁸O) in the natural abundance range and of H and O concentrations in organic and inorganic solid and liquid samples using a TC-IRMS coupling.
• Substance specific determination of N, O and C isotope abundances (δ¹⁵N, δ¹⁸O, δ¹³C) of atmospheric trace gases (specifically N₂O and CH₄) in the natural abundance range using a PreCon-GC-C-IRMScoupling.
• Simultaneous determination of C and N isotope abundances and of C and N concentrations in organic and inorganic solid samples from tracer experiments using an EA-IRMS coupling.
