NBS 19 calcium carbonate, L-SVEC lithium carbonate, and IAEA-CO-1 calcium
carbonate were analyzed by Qi et al., Two new organic reference materials
for delta 13C and delta 15N measurements and a new value for the delta 13C
of NBS 22 oil, Rapid Commun. Mass Spectrom., v. 17, 2483-2487 (2003).
Analytical details for EA combustion are given therein.

Hi,

Anybody has tried to run carbonate for d13C with EA? How high is the
combustion temperature?  I am afraid 1030 degree C is not enough. Any other
tricks should be aware of?

Regards.
