When requesting for an estimate/quotation, please provide the currency, number of samples, service requested/turnaround time (AMS standard or priority), type (non-heated, fully charred or cremated bones) and the billing address.
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).
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.
Do not place extracted collagen directly into Ziplock bags.– 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.
The bone sample is first tested for friability (“softness”).
