Radiocarbon dating sample preparation

The samples are placed in big tubs in which exchange of acid and buffer are computer monitored. Once digested we use equipment to get rid of clay particles right. Depending on the nature of the sample residue it is separated magnetically or by means of density applying sodium polytungstate. The resulting sample residues are dried and subdivided into different fractions.

One of the basic assumptions in carbon dating is that the sample being analyzed has undergone only radioactive decay and has remained unaltered by any other process over the years since it ceased interaction with the biosphere. This assumption, however, is rarely true. The archaeological artifacts and geological specimens sent to labs for radiocarbon dating are usually found embedded or buried with other materials that may have affected their radiocarbon content. Any carbon-containing material that affects the carbon 14 content of any given sample is therefore a contaminant.
