Ams carbon dating
Typically, this is NZD100 for pretreatment and NZD200 for pretreatment and combustion, but charges may vary depending on the sample type.
All samples that have undergone pretreatment and subsequently found to be unsuitable for dating, or abandoned for another reason, may incur a part charge.

An assessment is made of the credibility of the radiocarbon dating of the shroud of Turin.
The quoted final results produced a calibrated calendar age range of AD 1260–1390 for the linen of the Turin shroud at a 95% confidence level.
It is suggested that steps should be taken to conserve the shroud and that permission should be given for its examination by experts in medieval art.

This article summarizes the use of accelerator mass spectrometry (AMS) for radiocarbon dating measurements.
It expands on the principles already laid out in the articles on Principles of Radiocarbon Dating and 00040.
At the Laboratory, aside from modern and background standards, routine in-house measurements are also made on standards of like composition and age to the sample being dated.
The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere. This makes it possible to tell the age of substances that contain carbon. Dates obtained are usually written as before present ('present' is 1950).
