Stable isotope analysis

Stable isotopes are increasingly being used as tracers for dietary habits (mostly carbon; 13C/12C), trophic positions (nitrogen; 15N/14N) and migratory movements (hydrogen and oxygen; 2H/1H and 18O/16O) of animals. The stable isotope laboratory at the IZW is equipped with state-of-the-art isotope ratio mass spectrometers (Delta V Advantage, Thermo) connected to a peripheral elemental analyser (Hekatech-Elemental analyser, Flash EA from Thermo and TC-EA from Thermo) to measure these elements in any organic tissue (C, N, H and O), gas (C, H and O) and liquid (H and O). Depending on whether or not the matrix has natural enrichments or whether it is artificially enriched, we provide measurements in the delta-notation (in relation to an international standard) or in atom percent. Turnaround times are quite fast for standard material such as plant or animal tissues (usually less than 1 month).

Depending on the enrichment of CNH in your sample, we need a sample volume of 0.4 to 1.5 mg. You may either send us the raw material or you may prepare your samples for stable isotope analyses using our facilities.
