Dear colleagues,

I consider to buy CO2 gas and would be thankful for any information regarding
commercial tank CO2 gases purchased recently: their d13C and d18O, manufacturer,
and if known, the origin of the gas (e.g. fuel combustion). Despite I am
interested in manufacturers in Germany, information from other countries is of
interest as well.


Best regards,

Sergey
