Established in 2007, our accelerator mass spectrometry facility continues a legacy of radiocarbon dating at Queen’s that began in 1969. Our experienced team have reported at least 30,000 high quality dates for use in both environmental and archaeological studies.
The 14Chrono Centre provides radiocarbon (14C) dates and stable isotope analysis as well as statistical chronological models for both research and commercial projects in a wide range of disciplines including archaeology and environmental sciences.
Accelerator Mass Spectrometry (AMS) is a technology that allows us to distinguish and detect different types of atoms on the basis of differences in atomic weights (mass). Major advances in the application of this technology to radiocarbon dating were made in the 1980s and it has since become the dominant method used in radiocarbon labs worldwide.
