You can find more videos like Compound specific radio carbon dating process below in the related videos section. For radiocarbon results to be accurate, samples must be free of contaminating carbon. Sample pre-treatment using a high-performance liquid chromatography HPLC approach has been developed at the Oxford Radiocarbon Accelerator Unit ORAU as an alternative to conventional methods for dating heavily contaminated bones. This approach isolates hydroxyproline from bone collagen, enabling a purified bone-specific fraction to then be radiocarbon dated by accelerator mass spectrometry AMS. Using semi-preparative chromatography and non-carbon-based eluents, this technique enables the separation of underivatised amino acids liberated by hydrolysis of extracted bone collagen. A particular focus has been the isolation of hydroxyproline for single-compound AMS dating since this amino acid is one of the main contributors to the total amount of carbon in mammalian collagen. Once the organism dies, the only process affecting the 14C content of the original tissue is radioactive . made that could permit radiocarbon dating of individual.
