Stable carbon isotope studies of gas exchange within terrestrial ecosystems are commonly undertaken to determine sources and rates of carbon cycling.

Septum-capped vials were filled with standard gases of varying CO2 concentrations (~700 to 4000 ppm), δ13C values (approx. -26.5 to + 1.8‰V-PDB) and pressures (33 and 67% above ambient), and analysed after a storage period of between 7 and 28 days.
