The RWI Stable Isotope Labs are equipped for the analyses of stable water isotopes (δ18O, δ2H) in groundwater and experiment solutions.
Stable water isotopes (δ18O, δ2H) in groundwater and experiment solutions are analysed using Cavity Ring Down Spectrometry CRDS [Picarro L2120-i]. Standardisation ranges cover the normal δ18O, δ2H range observed in snow, ice and groundwater from cold and warm climate regions. In addition different Lab-internal standardisation ranges exist for high-D contents for the analyses of experiment solutions traced with deuterium (D).
The quality of δ18O, δ2H analyses is ensured by regular measurements of IAEA approved control standards regular participation in comparative tests with other isotope laboratories.
