We have analysed the element composition and the context of particles
collected within the coma of 67P/Churyumov–Gerasimenko with Rosetta’s
COmetary Secondary Ion Mass Analyzer (COSIMA). A comparison has been
made between on board cometary samples and four meteorite samples
measured in the laboratory with the COSIMA reference model. Focusing on
the rock-forming elements, we have found similarities with chondrite
meteorites for some ion count ratios. The composition of
67P/Churyumov–Gerasimenko particles measured by COSIMA shows an
enrichment in volatile elements compared to that of the investigated
Renazzo (CR2) carbonaceous meteorite sample.
