Dear Isogeochem

I am looking for a good and simple offline preparation technique to combust pure methane for d13C determination on dual inlet.

Previously I have added my solid or liquid sample to CuO and evacuated it in a sealed glassampulle. Then combusted it into a furnace oven, before drying the CO2 before using the dual inlet.

I guess there is something similar for gases too. But how do I introduce my gas to the ampulle? I hope I don’t need to reinvent the wheel.

Hilsen/Regards
