Compound specific radiocarbon dating Jasmin live free chat bosnia
Selecting the appropriate pretreatment plan depends on the unique attributes of the sample itself, such as the sample type, potential contaminants, the burial context, and the size and preservation of the sample.
Communication between the radiocarbon researcher and the sample collector is integral to this process.
This may involve cleaning to remove obvious contaminants and/or reduction of particle size of the sample.
We are happy to include calibrated calendar ages in your report. Sample Pretreatment for AMSIn general, it should be assumed that all samples are affected by some form of alteration or contamination.
