While the lighter isotopes C has decayed that what remains can no longer be measured. In 5,730 years half of the C in the atmosphere, and therefore in plants and animals, has not always been constant.

A (federally-funded) handling and analysis surcharge applies to small samples (2-9 µmol).
A 0 (federally-funded) surcharge applies to high precision analysis (minimum batch size 5 samples). Additional fees may be assessed for preparation of samples not ready for routine processing, samples which yield no analyzable carbon or those withdrawn at client request.
Rachel Wood does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond the academic appointment above.
The lab also provides stable isotope analyses on a standalone basis.
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 NZD100 for pretreatment and NZD200 for pretreatment and combustion, but charges may vary depending on the sample type.
It has forwarding offices in Australia, Brazil, China, Japan, South Korea, Taiwan, and the UK.
Beta Analytic’s radiocarbon dating fees are inclusive of δ13C measurements by Isotope Ratio Mass Spectrometry (IRMS) and calendar calibration when applicable, δ18O for carbonates, and δD (deuterium) and δ18O for water.
