Determinations of all organic carbon containing material is available, such as seeds, wood, charcoal, peat, bone and fabric but also from inorganic carbon such as carbonate of burnt bone, carbonate shells of shellfish and foraminifera.
The laboratory also provides biofraction determinations from samples such as mixtures of different kinds of liquid fuel (biodiesel-fossil diesel etc.), plastics, or different gaseous samples.
From its first radiocarbon measurement in 1951 to the installation of a new compact AMS in 2010 this facility has been at the forefront of radiocarbon analysis. We provide a full radiocarbon dating service for research and commercial clients worldwide.It cannot be applied to inorganic material such as stone tools or ceramic pottery.The technique is based on measuring the ratio of two isotopes of carbon.In just the past 10 years over 25,000 samples have been measured from clients in New Zealand and throughout the world.As well as the AMS facility, the Rafter Radiocarbon Laboratory operates a modern, well equipped sample processing laboratory.The laboratory provides luminescence dating services. It is advisable to read up on sampling beforehand, in order to avoid possible problems.
