Comparison of soluble and insoluble organic matter in analogues of Titan's aerosols

- First molecular characterization of the different fractions of tholins by LDI-FTICR.
- Insoluble fraction in methanol represent 65% of the bulk sample.
- Insoluble fraction present very different chemical structure than the soluble one.
- Insoluble fraction present a significant higher amount of unsaturations.
