A researcher in archeological chemistry in a lab at the Oxford Radiocarbon Accelerator Unit loads a sample for purification using supercritical carbon dioxide as an extraction agent or solvent to remove contamination. In the sensitive technique of radiocarbon dating organic samples any impurities may affect the results and use of the supercritical CO2, which exhibits properties of both a gas and a liquid, is hoped to lead to improvements in accuracy.
