International audienceFor the last ten years, quantitative isotope ratio monitoring C-13 NMR (irm-C-13 NMR) has been successfully tested and proven as an efficient tool for the determination of position-specific C-13/C-12 ratios. Several applications in different domains have shown the interest in this technique. In the context of origin assignment, the possibility to track the distribution network of illicit drugs or cutting agents is of prime importance. However irm-C-13 NMR still suffers from a relative lack of sensitivity limiting its dissemination among control laboratories. Improvements were proposed to reduce experiment time by using the INEPT sequence (''Insensitive Nuclei Enhanced by Polarization Transfer'') based on polarization t...
