In the Isotope Laboratory, stable isotopes of carbon, nitrogen, oxygen, and hydrogen are investigated by determining the ratio of individual isotopes (atoms of one element whose nuclei contain different numbers of neutrons) in the sample material. The isotopic composition of the sample allows conclusions about, for instance, the prevailing temperature and precipitation regime when the material was formed. In addition to paleoclimatology, stable isotopes are also utilized in geological, biological, and archaeological research. Applications range from forensics to hydrogeology.
The laboratory is equipped with two Thermo Scientific DELTA V IRMS, a Thermo Scientific DELTA PLUS IRMS, two EA-1112 CHN analyzers coupled to the IRMS for the analysis of organic matter in sediments or biomasses, two Thermo Finnigan GASBENCH II analyzers for investigation of carbon and oxygen isotope ratios in carbonate and liquid samples, and a PICARRO Model L1102-i Cavity Ring Down Spectrometer for isotope analysis of hydrogen and oxygen in water samples.
