Laboratory studies of tholins, analogues of Titan aerosols, with the LAb-CosmOrbitrap

International audience; Instruments on the Cassini-Huygens mission have allowed the collection of a big amount of data about Titan and revealed part of the complex organic chemistry in the dense atmosphere of this moon. Complementarily to the data received, analyses of laboratory analogues of Titan aerosols help the understanding of chemical mechanisms occurring on Titan. These analyses are also preparing the new generation of space mass spectrometer, such as the LAb-CosmOrbitrap, new high-resolution mass analyser based on the Orbitrap TM technology and coupled with laser ablation ionisation.
