A scientist examines the HPLC yield of purified protein derived from a complex mixture of material, as research into improving the accuracy of radiocarbon dating. In converting an organic sample to graphite, for use in the accelerator mass spectrometer (AMS) the yield of original material has an effect on the accuracy of the data used to calculate the age of the original sample. Photographed at the Oxford Radiocarbon Accelerator Unit, University of Oxford, UK.
