  1. About radiocarbon dating

  2. What is Radiocarbon Dating? Carbon-14 dating is a laboratory analysis that provides objective age estimates for carbon-based materials that originated from living organisms such as archaeological finds or geological deposits.

  3. Limitation Cannot be used for samples older than ~ 60,000 years (Reported as greater than 43,500 BP by Beta Analytic)

  4. Liquid Scintillation Counter (LSC) Accelerator Mass Spectrometer (AMS) Machines Used

  5. AMS is more Advanced than LSC • AMS is more accurate and precise • Sample sizes are smaller • Analysis takes less time

  6. Why Measure δ13C? To provide accurate and precise Carbon-14 measurements, it is necessary to correct for “isotopic fractionation” using the stable isotopes 13C and 12C (δ13C). Researchers should also find out whether the δ13C was measured in the AMS or in an isotope ratio mass spectrometer (IRMS). If it is the AMS δ13C, it cannot be used for dietary or metabolic pathway studies.

  7. Information compiled by ISO 17025-accredited radiocarbon dating lab Beta Analytic. For more information, please visit https://www.radiocarbon.com.
