Abstract
At least one type of carbon material susceptible to generate a gas G is selected. Then, a model is built from the carbon isotopic composition of a gas P generated by thermal degradation of this type of carbon material. The model is calibrated by calibrating the kinetic effect independently of the precursor effect. In order to achieve that, pyrolyses are performed on compounds modeling the type of carbon material, said compounds being synthesized and labeled withC. Using said model, a carbon isotopic composition of gas P generated is estimated. Finally, it is determined whether gas G has been generated from the selected type of carbon material, by comparing a measured isotopic composition of gas G to the estimated isotopic composition.
