Thermal evolution of organic residue and TOF-SIMS analysis in the framework of the COSIMA experiment.
Abstract
We have developed a new experimental setup allowing the study of thermal evolution of macromolecular organic compounds up to 800 K. We will present the first results concerning POM (polyoxymethylene - H2CO polymer) and HMT (hexamethylenetetramine - C6H12N4) heated at high temperature (300 - 800 K). The relevance of the results for cometary and meteoritic studies will be enlightened. Some organic residues have also been analyzed with a mass spectrometer similar to COSIMA allowing the preparation of the interpretation of the data of the time of flight mass spectrometer on board the Rosetta mission.
