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 you require ultrafiltration, please contact us before sending your samples.
Please use this contact form to inquire on radiocarbon dating prices.
– 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.
– 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.
This many times requires both physical abrasion of the surface and chemical treatments.To assess the quality of the preserved collagen, the sample is demineralized in dilute/cold acid to eliminate all apatite and carbonate after physically or chemically removing the outer exposed surfaces.The collagen is then dissected and inspected for rootlets.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, and C: N values at no additional cost for non-cremated bones submitted for AMS dating.
We recommend wrapping the sample in Aluminum foil or using a plastic or glass vial with a screw top before placing in a Ziplock bag.
