67.石炭液化油のHPLC/GC-MSによる化合物タイプ同族体成分の同定  [in Japanese] 67. Identification of Compounds in Coal Liquefaction Oil as Compound Type Homologue by HPLC/GC-MS Analyses  [in Japanese]

Aromatic ring class fractions separated by NH_2 column HPLC were analysed low and high voltage mass spectra by GC-MS. Various compound type defined by Z numbers were determined and Z mass chromatograms were measured as homologous series. Respective peaks of Z number mass chromatograms were assessed the degree of coelution with different components and GC peaks belonged to single component were measured on HV mass spectra to assign the specific components.
