we ordered CO2 with enriched (or “natural”) d13C through AirLiquide in Germany. I have to look up the contact person.
However, the price quote was astonishing high - compared to standard CO2 (deepening on the supplier 45,- to 180,- EUR/6.5kg). When I recall correctly the price for the special delivery option was about >1000,- EUR/6.5kg bottle.
It also possible to get it for example through Linde. The trick is that you have to convince the sales person that you need the CO2 from a specific site; in that case this is a natural CO2 source at Herste, Germany (d13C about -3.5%o). That gas ist typically used in the food industry and for soda makers. However, in most cases the sales representative will tell you that it is just not possible (or only for a enormous price) to trace a bottle from a specific production site to your lab.
I typically try trust to my luck and order one of the cheap cylinders and just see what I get...
