dc.description.abstract© 2023, The Author(s) under exclusive licence to Associação Brasileira de Engenharia Química.Fourier transform ion cyclotron resonance mass spectrometers (FT-ICR MS) play a major role due to their capability to provide information at the molecular level of complex samples. However, asphaltenes deposition in capillaries during ionization hinders the analysis of unstable fractions. To overcome this, in our previous work (10.1016/j.fuel.2022.124418), we demonstrated laser desorption ionization (LDI) as an alternative to FT-ICR MS analysis of unstable asphaltene fractions without the occurrence of any capillary obstructions. Herein, a simplified fractionation methodology for separating asphaltene fractions according to their structural motifs is presented. Then, the asphaltene fractions were characterized by LDI (+) FT-ICR MS. Moreover, structural characterization was also performed Collision-Induced Dissociation (CID) experiments.
