In this video, she compares conventional and accelerator mass spectrometry AMS radiocarbon dating. AMS is faster and needs a much smaller sample, but is more expensive. Also shown are views of bone preparation at the Waikato Radiocarbon Dating Laboratory.

This means small samples previously considered to be unsuitable are more likely to be datable; scientists can now select from a wider range of sample types; dates can be made on individual species or different fractions; greater numbers of radiocarbon measurements can be made resulting in more detailed chronological evaluations; more stringent chemical treatments can be applied to remove contaminants; and valuable items can be sub-sampled with minimal damage. Consequently, AMS dating is invaluable to a wide range of disciplines including archaeology, art history, and environmental and biological sciences. Because of the wide range of different materials that can now be dated we recommend you contact us first to discuss your 14 C requirements. The construction of 4 new AMS CO 2 and graphitisation lines in has enabled us to quadruple our throughput and reduce our turnaround time for AMS now averaging 6 weekswhile maintaining our quality controlimproving our background limits and reducing sample size requirements.

Radiocarbon dating is one of the main lines of evidence of Polynesian arrival some time between and Since the s, when this method was developed, scientists have learnt more about its application in the New Zealand setting. For example, they have found that some materials such as moa eggshells can generally be more reliably dated than others such as the bones of omnivores.

All the samples sent to the Laboratory should be accompanied by Waikato Radiocarbon Dating Laboratory sample submission forms. Please take time out to fill out the details on the submission forms. They will stay with the sample records in the database, and are available for future reference.

Please contact us for collaborative research and bulk discount prices. All samples that have undergone pretreatment and subsequently found to be unsuitable for dating, or abandoned for another reason, may incur a part charge. Typically, this is NZD for pretreatment and NZD for pretreatment and combustion, but charges may vary depending on the sample type. Please read our pages on sample weight requirementsand if you are unsure about the suitability of your sample please contact us.

Historical artefacts like moa bones can be dated using a technique that measures the activity of the radioisotope carbon still present in the sample. By comparing this with a modern standard, an estimate of the calendar age of the artefact can be made.
