Dear Rajesh,

A brief description of how to measure "simultaneously"
d13C and d15N from the same organic compound in one analytical
run (GC/C-IRMS) can be found in my forthcoming paper which will be
published by the end of this month. Unfortunately, I haven't received
the reprints yet but if you would bear with me I should be happy to
send you one as soon as poss.

Here is the reference:

W. Meier-Augenstein: “Applied GC coupled Isotope Ratio Mass
Spectrometry”, J. Chromatogr. A., 842, 343-363 (1999).

However, I'm not entirely sure if that's what you are looking for.
Your question seems to suggest bulk isotopic composition,
i.e. elemental analyzer - IRMS work. Maybe the chaps at Finnigan
(Bremen) can help you with that.


Cheers,

                      Wolfram
