Zur Hochdruck-Fl�ssigkeits-Chromatographie von polycyclischen aromatischen Kohlenwasserstoffen

High performance liquid chromatographic separation of polycyclic aromatic hydrocarbons on microparticulate pyrrolidone and application to the analysis of shale oil

“…Goldstein reported that polyvinylpyrrolidone) separated PAHs according to the degree of aromaticity and also according to the manner of aromatic ring condensation. This kind of selectivity is quite unique in comparison to the selectivity of both silica (19,20) and octadecyl bonded phases (21,22), whose retention characteristics are affected by aliphatic substituents. Wise et al recently reported the separation of PAHs on a chemically bonded microparticulate amino phase (23).…”

Gas chromatographic mass spectrometric determination of high-molecular-weight polycyclic aromatic hydrocarbons in coal tar

“…From the theoretical point of view, high-performance liquid chromatography (HPLC) is the best method for analyzing high boiling substances. Thoms and Blümer were successful in separating PAH of molecular weights up to 598 in a test mixture (9,10) and, under the same conditions, in coal tar (11,12). Recently, Peaden et al (13) separated PAH in the molecular weight range from 202 to 448 in carbon black, using reversed-phase C18 columns.…”

“…FD ionization of benzo[a] pyrene/DNA adducts has been shown to produce sufficient ion beam for MS/MS analysis by B/E linked scans (8). A method of analysis of mixtures of surfactants has been developed recently which makes use of FD ionization and MS/MS analysis with a tandem magnetic sector instrument equipped with a channeltron electron multiplier array (CEMA) detector (9). The instrument permits simultaneous detection of small portions of the CID spectrum which is a real advantage for study of the weak, short-lived, and often fluctuating ion currents produced by…”
