  • Publication number: 20190353616
    Abstract: A method identifies the molecular structure of each component in a multicomponent mixture. The method includes (1) subjecting the multicomponent mixture to mass spectrometry to identify the formula of a molecule attributed to each obtained peak, and to identify abundance of the molecule; (2) subjecting the multicomponent mixture to collision induced dissociation; (3) performing mass spectrometry on each fragment ion generated via the collision induced dissociation in (2) to identify the core structure forming each fragment ion and abundance thereof; (4) dividing the molecules attributed to each peak in (1) into “classes” based on “a type and number of heteroatoms, and a DBE value”, and on all the molecules belonging to each “class”, estimating the existence state and abundance thereof; and (5) determining the core structure forming each molecule, for which the existence state is estimated in (4), and determining and assigning a side chain and a cross-link thereto.
