The carbon dioxide is collected and bubbled through various chemicals in the line, which purify it, and the amount of carbon dioxide that has been collected is measured.To obtain a calendar age for the sample, this radiocarbon age needs to be compared against samples of known age by means of a calibration curve using a specially designed computer software application.This application uses a terrestrial calibration curve to calculate the calendar age.The decay events for each sample are measured over a week.The results from the liquid scintillation spectrometer are carefully analysed and provide a radiocarbon age for the sample.
