Dear Frank Pawellek,

We are currently running a large batch of organic carbon samples and would
be happy to analyse some of your cellulose. At present we normally run
NBS22, ANUS(ucrose) (now given a less "offensive" IAEA name which I can't
remember) and an internal graphite standard to check the reproducibilty
and accuracy of our analyses. If you want we can send you some of our graphite
in return.

By the way, if you include your e-mail with your isogeochem messages it will
save everyone else receiving boring messages like this one.

Regards,

Steve Crowley
