|Abstract:||We tested direct injections of headspace gas into a Gas Chromatography - Combustion - Isotope Ratio Mass Spectrometry (GC-C-IRMS) system to measure 13C/12C isotopic ratio of carbon dioxide from the headspace of several sparkling and soft drinks. This simple and straightforward technique improves the determination of delta13C values of CO2 gas as a food probe of authenticity. However for an ultimate test, combination with other isotopic data is required.|
