Abstract : For two years, the time-of-flight secondary ion mass spectrometer COSIMA (COmetary Secondary Ion Mass Analyzer), on board the Rosetta orbiter, performed in situ analyses of the dust particles ejected from the comet 67P/ChuryumovGerasimenko. Exploiting different analyses of organic analogs that have been analyzed via the COSIMA reference model, we are now able to estimate the H/C elemental ratio of the 67P cometary particles.
