Abstract

Ion/molecule reactions between fluorocarbon cations, generated from perfluorotributylamine (FC43), and polycyclic aromatic hydrocarbons (PAHs) were carried out in a quadrupole ion trap by mass isolating individual types of FC43 ions (R+) and reacting them with PAHs eluting from a GC column. The observed products resulting from these reactions consisted of [M + R](+) adducts and [M + R - nHF](+) (n = 1,2) elimination products. The relative abundance of these products was found to vary between different PAH structural isomers, such as anthracene and phenanthrene, thus enabling isomer differentiation. Of particular interest was the reactivity of the C3F5+ cation because this species yielded the most abundant and diverse reaction chemistry. Formation of adducts versus molecular ions appears to be strongly influenced by the ionization energy (IE) of the PAHs. Using this ion/molecule reaction technique several PAH isomers, present in a PAH contaminated environmental sediment extract, could be identified.
