Abstract
A method and system to determine mass fraction of aromatic hydrocarbons, sulfur-multi-sulfur, sulfur-nitrogen, multi-sulfur-multi-nitrogen, and nitrogen containing aromatic compound classes present within a petroleum sample. The invention uses total sulfur determination, total nitrogen determination, and elemental formulas determination, with the latter determined through time-of-flight mass spectrometric analysis with atmospheric pressure photo ionization and Fourier-transform ion-cyclotron resonance mass spectrometric analysis with atmospheric pressure photo ionization.
