Preparation and stable isotope ratio measurement (H, C, N, O, S) of wooden, skeletal or inorganic archaeological samples, helping in the interpretation of the results.
Stable carbon, nitrogen, sulphur and oxygen isotope ratio results (expressed in d13C, d15N, d34S and d18O, respectively) can be measured from the same samples using a Thermo Scientific Delta Q isotope ratio mass spectrometer coupled to an elemental analyzer (Thermo Scientificâ„¢, EA-ISOLINK CNSOH) or a gas bench (Thermo Scientificâ„¢, Gas Bench Plus) interface. These stable isotope results are very useful in palaeodietary, palaeoecology or paleoclimate studies.
