Radiocarbon dating bone samples
The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.
The lab also provides stable isotope analyses on a standalone basis.

University of Leicester archaeologists took four small samples from one of the ribs of the Greyfriars skeleton and sent them to two specialist units with the facilities to analyse them: the Scottish Universities Environmental Research Centre (SUERC) at the University of Glasgow, and the Oxford Radiocarbon Accelerator Unit, part of the University of Oxford’s Research Laboratory for Archaeology and the History of Art.
The small pieces of bone were combusted to produce carbon dioxide which was then put through a mass spectrometer.
The results of this study support that even if the C/N ratio of a degraded raw bone sample is 11, extraction of collagen for bone dating is feasible by a carefully designed ultrafiltration process. The C/N ratios of the collagen samples of Gunang-gul were determined to be 3.2? Our study establishes a new guide for the pretreatment of degraded bone samples such as those collected in Korea for 14C dating.
Our preliminary 14C dating results of a depth profile of Gunang-gul Cave, an archaeological site in Danyang, Korea, indicate that this site has been either geologically or anthropologically disturbed in the past, with 14C ages ranging from 28,910 ?
We have examined a few dozen Korean archaeological bone samples for this study.
Well-preserved bone samples are found to be physically dense.A wide range of sample types can be submitted for dating.We can advise on the suitability of different materials and the most effective pretreatments.The mass spectrometry of the Greyfriars bone samples reveals that the individual in question had a high-protein diet including a significant proportion of seafood.This would seem reasonable for a medieval nobleman, and certainly for a member of the royal family.Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).Tags: Adult Dating, affair dating, sex dating
