CLIPT Stable Isotope Laboratory
The CLIPT (CLimate Interpretation of Plant Tissue) lab measures carbon, nitrogen, oxygen and hydrogen stable isotopes on geological and biological substrates for the UiO community.
Contact the CLIPT Lab to set up analyses.

Description of Services:
Prices are for internal users (UiO affiliated). External users please contact the CLIPT lab for information and pricing
- δ13C and δ15N on bulk organic materials: 130 NOK
- δ13C only on bulk organic materials: 130 NOK
- δ15N only on bulk organic materials: 130 NOK

About the CLIPT Lab:
The CLIPT lab is a joint infrastructure facility at UiO shared between the Geoscience and Bioscience departments. It is part of the Centre for Earth Evolution and Dynamics (CEED) and affiliated with the Centre for Biogeochemistry in the Anthropocene (CBA).
CLIPT has been providing high quality stable isotope data to the UiO research community since its official opening in April, 2018. Among its multi-disciplinary user base are geologists, biologists, medical researchers, chemists, and archeologists, with research in the fields of paleoclimatology, Viking history, cancer cell growth, eco-toxicity, biologic trophic studies, resource allocation, and climate change.
The facility currently houses a Thermo Fisher DeltaV Stable Isotope Mass Spectrometer configured with a Flash EA Isolink system capable of high precision carbon, nitrogen, oxygen and hydrogen stable isotope analyses on bulk organic samples.
Additionally, an LC-Isolink System is available for carbon compound specific analysis on water soluble components such as sugars, amino acids and nucleic acids.
We welcome visits from interested researchers and students and are available to discuss your stable isotope analytical needs. Contact the CLIPT Lab to set up a meeting or to take a personal tour of the facility.
We are always looking for new ways to improve and expand our capabilities and encourage researchers to contact us about stable isotope analyses they are interested in that are not listed here.
Funding for the CLIPT lab comes from the Research Council of Norway through the Centre for Earth Evolution and Dynamics (CEED). The Institute for Biovitenskap (IBV) has provided lab space and infrastructure support, including instrumentation purchased off of a UiO Infrastructure grant.
