A vital step to radiocarbon dating rock paintings involves the characterization of organic material in the paint. Using THM-GC-MS we have created a library of mass spectrometric data on possible organic binders, to compare to authentic paint samples. To reduce interference from contaminants and the mineral background, we are developing a simple purification technique to extract proteins and carbohydrates from these samples. Separating the organics can greatly enhance our results for GC-MS identification and subsequent radiocarbon analysis by accelerator mass spectroscopy.
