The Earth science Stable Isotope Laboratory also caters to external research institutes and universities, as well as to research demands of private petrochemical and water companies.
Stable Isotope Analysis
The Earth Science Stable Isotope Laboratory routinely provides precise and accurate stable carbon (C), hydrogen (H), nitrogen (N) and oxygen (O) isotope measurements on biogenic and inorganic samples.
Innovation at the Earth Science Stable Isotope Laboratory comprises stable C and O isotope analyses of minute amounts of carbonate (<5 μg) and the H and O isotope analysis of fluid inclusions extracted from rock samples such as speleothems and hydrothermal minerals.
| Sample type | Isotopes |
| Carbonates (Calcite, Aragonite, Dolomite, (fossil) shells and foraminifera | δ18O and δ13C |
| Apatite (Bone and teeth) | δ18O and δ13C structural carbonate δ18O phosphate |
| Fresh- and saltwater | δ18O and δ2H δ13C (DIC) |
| Organic matter (from sediment, hair, collagen and diamonds) | δ15N and δ13C |
Fluid-inclusions in minerals (speleothems, corals, hydrothermal minerals) | δ18O and δ2H |
Fluid-inclusions in minerals (CO2 in quartz minerals) | δ18O and δ13C |
