The Reston radiocarbon laboratory performs research in the accurate C dating of different fractions of carbon that can be isolated from organic compounds such as sediments, soils and peat, which are often difficult to date reliably.

Established analytical procedures for radiocarbon dating are carefully applied to every sample the laboratory processes. The NERC Radiocarbon Facility (East Kilbride) is a central facility for the UK's Natural Environment Research Council (NERC), providing dating support in the environmental sciences.The laboratory has an "open-door" policy for all existing and potential users of its facilities at all stages of their research projects, and collaboration is strongly encouraged.As a chronology tool, C dating can provide ages for samples as old as 50,000 years.

The small sample size capability of AMS radiocarbon dating greatly expands the potential for dating geologic material previously undateable using older proportional counting methods.

In standard radiocarbon dating, scientists perform a limited or proportional count of the decaying C14 atoms.

In AMS dating, researchers use an accelerator-based mass spectrometer to count all the C14 atoms, rather than just those atoms which are decaying.

New methods are developed and tested as necessary to meet specific dating needs and to improve the overall accuracy and precision of the lab.

Radiocarbon dating by accelerator mass spectrometry (AMS) is an important analytical method utilized in climate change, land use change, ecosystems and natural hazards research. R., 2014, Evidence of repeated wildfires prior to human occupation on San Nicolas Island, California: Monographs of the Western North American Naturalist, v.

Definition: AMS (Accelerator Mass Spectrometry) radiocarbon dating is a way to obtain radiocarbon dates from samples that are far tinier than that needed for standard radiocarbon dating.
