Dating Options 

The Waikato Radiocarbon Dating Laboratory offers a range of dating options for our submitters depending upon the level of precision required and the sample size. We encourage researchers to contact us before undertaking any dating programme to discuss their samples and research objectives.
  • Express Option: An express service option is offered for urgent samples. Standard precision radiometric dates may be express dated in 10 working days (bone - 20 working days). AMS samples can be express dated in 4 weeks (please contact the lab for availability). This option is not recommended for older samples (>30, 000 years).
  • AMS Dating: Samples that are too small to be dated by the Standard Radiometric method can be dated by the AMS (Accelerator Mass Spectrometry) technique. Chemical pretreatments, CO2 production and graphitisation are undertaken at Waikato. Graphite is analysed at the Keck AMS Radiocarbon Laboratory, University of California, Irvine and the Center for Applied Isotope Studies, University of Georgia.
