I think you need to find your residue analyst who should advise. This
needs to be done by a specialist not only in organic chemistry but
someone who appreciates the problems of archeological sampling and
chemical change over time. My father as a trainee chemist was taught if
you have to split taking a sample and analysing it between a labourer
and a Phd chemist get the chemist to take the sample and the labourer to
analyse it.
