Stable isotope lab

We are equipped with a THERMO Flash 2000 elemental analyser interfaced to a THERMO Delta Advantage isotope ratio mass spectrometer and analyse ¹³C and ¹⁵N isotopes and CN elemental concentrations of organic matter samples. During analysis, samples are interspersed with several replicates of four different laboratory reference materials. These reference materials have been previously calibrated against the international reference materials IAEA-CH-3, IAEA-CH-6, IAEA-CH-7, IAEA-N-1 and IAEA-N-2. Moreover, we calibrated our IRMS to measure enriched CN stable isotopes up to 4 atom percent for ¹³C and 6.5 atom percent for ¹⁵N. Please contact Mario Brauns for more information.
