Overview of methods for improving radiocarbon dating accuracy through sample selection and treatment methods.
Accurate radiocarbon (14C) analysis depends on a successful carbon separation relevant to the studied object. The process of 14C dating involves the following steps: characterization and sample choice, sample treatment, measurements, and evaluation of the results. Here, we provide an overview of conventional approaches to macromolecular samples and address specific issues such as detecting and removing contamination with roots, dolomite, and conservation products. We discuss the application of elemental analysis (%N, %C) in the preparation of bones and the infrared analysis in monitoring the contamination of samples. Our observations provide the basis for the discussions of the existing results and for planning the future sampling.
