On the Responses of FID to GC Determination of Polycyclic Hydrocarbons

GC with FID was applied to the determination of polycyclic aromatic hydrocarbons (PAH′s),including naphthalene,phenanthrene,anthracene,fluoranthene and benzaanthracene.The concepts of molar carbon atom response (RC) and relative molar carbon atom response (RRC) were proposed,and regularity of change of RC and RRC of the PAH′s was also described.The numerical relationship between the number of of 2 different carbon atom C1 and C0 of the PAH′s and their responses (R) was obtained by multivariate linear fitting.
