Chemical analysis of dust produced in a N2-CH4 RF plasma discharge
Résumé
In order to simulate the reactivity of Titan upper atmosphere, CCP RF plasma discharge in a N2-CH4 gas mixture is used. The soluble and the insoluble fractions in methanol and toluene are analysed. The soluble fractions are analysed by massspectrometry (APPI-TOF), whereas the total aerosols and the remaining insoluble fractions are analysed and compared by IR spectroscopy and SEM microscopy.
