I have been analyzing samples for groups working on tree rings (d13C)
even if it is not my field of expertise (food, fraud,...). Now, those
colleagues are interested on going deeper on their contact with
"isotopes" and they showed their interest on analyzing d18O. Since my
experience is linked to other type of samples I had several doubts:
- which are the international stds people use for that? any WS to buy
- which advices are given for this kind of analyses? any issues to take
into account for having accurate results?.
