Carbon dating human

Spongy bones like ball and sockets, vertebra, and the like do not tend to preserve well in harsh conditions and may not yield sufficient collagen for AMS dating.

For bird and fish bones, please consult the lab for sufficient sample size.

If your samples are already powderized, please contact us for discussion.

We accept extracted bone collagen for radiocarbon dating.

However, the material will be listed as “organics” in the final report instead of “bone collagen.” This is due to the requirement by our ISO/IEC 17005 accreditation that if we did not perform the chemical pretreatments and/or extractions, we cannot specifically testify as to the material that was dated because certain steps affecting the sample quality have been outside of our control and scope of our accreditation.

– Fees are inclusive of d13C measurements, d15N measurements (except cremated bones), quality assurance reports, calendar calibration when applicable, and 24/7 web access to past results and pending analyses.

Additional fee is charged for collagen or bone carbonate extraction.

The d13C and d15N ratios are measured using an isotope ratio mass spectrometer (IRMS).We may not be able to provide d15N measurements for charred or heated bones depending on the sample quality. Beta Analytic also provides %C, %N, C: N and % collagen yield at no additional cost for non-cremated bones submitted for AMS dating.– It is important to understand the pretreatment applied to samples since they directly affect the final result.For bones, we provide conventional collagen extraction techniques and subsequent ultrafiltration methods if requested.If you require ultrafiltration, please contact us before sending your samples.Bones – Good cortical bone is best from the larger bones of the body (femur, tibia, upper arm bone, jaw, skull plate and sometimes the ribs).
