摘要：

We applied direct injections of headspace gas into a Gas Chromatography - Combustion - Isotope Ratio Mass Spectrometry (GC-C-IRMS) system to measure C-13/C-12 isotopic ratio of carbon dioxide from the headspace of several sparkling and soft-drinks. This straightforward technique, which consists in an automated analysis of the headspace sample with no prior purification steps, improves the determination of delta C-13 values of CO2 gas as a food probe authenticity. However, for an ultimate test, combination with other isotopic data is required. (c) 2006 Elsevier Ltd. All rights reserved.
