Abstract:
Gas composition in the headspace gas was measured by an Agilent 7890A gas chromatograph with flame ionization detector in the KIGAM. The carbon isotopic ratios of CH~4~ and carbon dioxide (CO~2~) in eadspace gases were analyzed using a compound-specific isotope ratio-monitoring gas chromatograph/mass spectrometer at Isotech Laboratories Inc., USA.
