The tooth enamel will have protected the dentin from loss.Miami radiocarbon lab Beta Analytic offers AMS dating for bones and teeth.Among these, the C/N atomic ratio is considered a good parameter for detecting low-quality collagen and possibly contaminated samples.In a combustion and graphitization setup like that installed at INFN-LABEC, Florence, measurement can be easily performed using an elemental analyzer when combusting the sample prior to graphitization, thus requiring no extra effort (or extra amount of sample) during the preparation procedure.Results of the redating of bone of Late Middle and Early Upper Paleolithic age from the British Isles and Europe suggest that we may need to look again at the traditional chronology for these periods.

radiocarbon dating on bone-89

The most suitable methods depend on the state of preservation of the bone, the type of environment, and the radiocarbon content; bones are classified according to different categories, and the appropriate methods indicated for each category.

In this paper, the methodology is described, and it is shown that, in many instances, ultrafiltration successfully removes low molecular weight contaminants that less rigorous methods may not.

These contaminants can sometimes be of a different radiocarbon age and, unless removed, may produce erroneous determinations, particularly when one is dating bones greater than 2 to 3 half-lives of 14C and the contaminants are of modern age.

Bones that have been exposed to water for long periods of time may not have enough collagen.

Most of the time, the collagen proteins had been leached out of the bone leaving them unsuitable for radiocarbon dating.
