Radiocarbon dating and stable isotopes

The Centre for Isotope Research offers radiocarbon (14C) dating by AMS of the highest quality, and additional stable isotope ratio measurements by IRMS on the elements H, C, N and O. Our analyses are only available for scientific, forensic and industrial purposes. This means that;

We will no longer accept samples for dating of artwork, craftwork, antiques or antiquities for commercial customers. For customers of scientific or cultural heritage organisations who want to investigate such samples (artwork, craftwork, antiques and antiquities), we have prepared a declaration to be signed prior to their submission. This declaration form can be requested via cio;

We do not accept ivory samples from any customer, except for (governmental) forensic investigations;

We do not accept samples from private customers.
