For small samples, blank contribution as a fraction of sample mass becomes a more important term, so a mass balance blank correction is applied.This correction is performed as follows: $$Fm_ = Fm_ ( Fm_ - Fm_b)\frac$$ Where \(M\) is sample mass, and \(M_b\) and \(Fm_b\) are the mass and Fm of the blank.
After acceleration and removal of electrons, the emerging positive ions are magnetically separated by mass and the C counts per second are collected.

Current projects involve researching the history of Arnhem Land ancestral sites in northern Australian, surveying and excavating shell mounds across Cape York Peninsular, studying the high-resolution store of information about past environmental conditions from sub-fossil kauri logs and identifying how Asian civilisations emerged.
Our research takes us all over New Zealand and the world to areas such as southern China, northern Australia, and Southeast Asia.
