I was wondering if anyone has measured carbon isotope ratios for an IAEA
standard: cotton cellulose (IAEA-V-9).  It is a reference material for
trace and minor elements, but I wondered if anyone had measured its delta
13C.  Please respond directly to me, unless you think everyone is
interested.

Thanks,
Franesca
