Earth Science Stable Isotope Laboratory - Vrije Universiteit Amsterdam

The Earth Science Stable Isotope Laboratory of the Vrije Universiteit (VU, Amsterdam, the Netherlands) plays an important role in the work of many researchers and students of different clusters of department of Earth Sciences at the VU, who wish to answer questions covering a wide range of academic disciplines: (carbonate) geology, palaeontology, hydrology, palaeoceanography,(paleo-)climatology, archaeology, forensics and planetary sciences.

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
