The sample is then washed with HCl, rinsed and dried.

We will perform cellulose extraction and solvent extraction upon request at additional cost.

The total organic fraction is isolated with a HCl wash which removes inorganic carbon and absorbed CO, rinsed and dried.

Solvent extraction may be necessary to remove conservatives or glues.These undergo similar pretreatment to marine shell samples. Freshwater and terrestrial shells may obtain their carbon from a source (or reservoir) that is not well documented and may give results that are difficult to interpret. We recommend contacting the lab before dating bone for the first time.All bone should be identified to species before dating.
