1. a kind of method for determining the core in heavy petroleum hydrocarbon, the heavy petroleum hydrocarbon have aromatic kernel and at least 343 DEG C at the beginning ofBoiling point, this method includes:

  • In a mass spectrometer by the heavy petroleum hydrocarbon soft ionization with formed have 400 to 1350Da molecular weight molecular ion andQuasi-molecular ion, ion, the ion of deprotonation or cation of the quasi-molecular ion comprising protonation or anionMolecular addition compound;

    WithPass through the ion in the collision induced dissociation and collision cell under the impact energy in the range of 83.7kJ/mol to 167kJ/molConcentration and Other Instruments parameter implement the controlled fragmentation of the molecular ion and the quasi-molecular ion, to be only broken described pointDaughter ion and the quasi-molecular ion include heteroatomic aliphatic key, so as to produce the aromatic kernel that C1 to C3 replaces.
