Ziplock Bags (place in Aluminum foil if sample is small or can be crushed during shipment) Please send your samples in small boxes instead of envelopes to protect the samples.
In effect, they provide us with windows to past societies, and contribute to our knowledge of ancient human evolution and cultural development.
Hard tissues contain an organic phase (mainly the protein collagen type I) embedded in a mineral phase (made of a non-stoichiometric biogenic apatite).
We routinely provide d15N testing on bone collagen.
For other material types, please contact us for discussion.
Collagen extraction fee applies in addition to the standard price.
Please use this data sheet when submitting samples for either d13C or d15N analyses NOT in conjunction with C14 dating. *** Use small vial and fill to the top with no headspace.
Please contact us at [email protected] you are in doubt about the suitability or weight of your sample.* Minimum quantity requested is 300 micrograms of carbon after pretreatment.
The advent of accelerator mass spectrometers (AMS) in the eighties revolutionized the field of archaeology by allowing smaller samples to be measured.
While it decreases the amount of carbon required for a radiocarbon measurement by several orders of magnitude, the AMS dating of bone collagen still requires at least 60–200 mg of bone, depending on the protein preservation and the extraction protocol.
