Dear all,

I am looking for a supplier in Europe of CO2 gas cylinders that has d13C 
more enriched than typical organic matter: d13C in the order of ~ -10‰ 
or higher.
In the past I used CO2 produced as a byproduct of corn ethanol, supplied 
by Airgas in some parts of the USA. However, Airgas do not sell 
internationally. Does anybody in Europe have such tank and can tell me 
which company did you buy it from?
