Polycyclic aromatic hydrocarbons PCAH

Polycyclic Aromatic Hydrocarbons. Gas chromatographio-mass spectrometric analysis of fractions 31-91 indicated the presence of various polycyclic aromatic hydrocarbons (PCAH) with molecular weights of 178-316. Because it is impossible to discuss in detail all die chromato-... [Pg.193]

Our mass spectrometric studies have shown that major ions < 500 amu are consistent in mass with polycyclic aromatic hydrocarbon (PCAH) ions. Experimental ion mobilities of a wide mass range of PCAH ions (j, ) were extrapolated to very high masses in order to estimate the mobilities of the heavy median mass ions (Figure 1). This extrapolation parallels a Langevin-type equation. [Pg.37]
