More than 10 000 datations for the Carbon-14 lab!
October 5, 2021

During the month of August 2021, Guillaume Labrecque, head of CEN's Carbon-14 radiochronology laboratory, performed the 10,000th AMS (Accelerator Mass Spectrometry) dating in the history of the laboratory. This is an important milestone for this CEN laboratory which serves scientists, but also private, municipal and governmental clients from here and from several countries.


Did you know that?

  • Radiocarbon dating is possible for all organic samples (wood, charcoal, seeds, peat, sediments, plants, roots), shells (and carbonates) and also bones (and teeth, ivory, animal horn...)?
  • The quantity required for dating with the AMS method is minimal: 1 mg (wood and charcoal) to 1g (bones)?
  • The margin of error of samples dated by the CEN laboratory is among the lowest  compared to other laboratories offering the same service?
  • CEN members and university clients benefit from advantageous rates for the dating of their samples.
