Dear Listmembers,
Sorry for my previous reply, which was in Dutch, but i intented to
send it to Richard's private e-mail adress. For those people that are
interested (or want to learn some Dutch), here's the translation of
what I wrote him:
"Sorry for the late respond, but I'm just back from a holiday.
We will also measure 13C in CH4 in the future, using our Anca-tg2
(pdz). For the moment I cannot give you any tips or adresses
where you can buy such reference material, but i'll keep you
informed when we find something.
In the meantime we will probably buy CH4-gas at natural
abundance and have it calibrated, to use it as reference-material."
Again, i'm sorry all of you had to read the Dutch version...
Best regards,
Peter Vervloedt
