Higher precision is available on request.
The preferred minimum sample size is 2.5 mg carbon. The sample sizes quoted in the list above will yield approximately 2.5 mg carbon if the samples are well-preserved. For low-carbon organic material the carbon content can vary widely and no estimate for the preferred minimum sample size can be given. Smaller sample sizes can be dated at a reduced precision. If samples require additional processing, the submitter will be informed of the added cost before work proceeds.
