Undersized Samples

Undersized Samples

Radiocarbon dating is a necessarily destructive process.  DirectAMS established recommended minimum submission sizes for each sample type to assure that a reserve of material will be available in the unlikely event that sample material is destroyed during chemical pretreatment, or if an AMS measurement fails to yield reproducible data.  DirectAMS absorbs the cost of reprocessing failed samples.  Undersized samples afford only a single opportunity to process material, therefore DirectAMS cannot guarantee a date.  DirectAMS will notify the Submitter of all small mass sample submissions to obtain approval for processing.  If approved, a processing fee of $100 will be assessed sample processing fails to yield sufficient material for AMS measurement. The full cost of analysis will be assessed if AMS measurement of the sample fails
