“…GC/MS is widely used for group-type analysis of petroleum products, determining paraffin, olefin, naphthene, and aromatic (PONA) fractions. GUMS analysis of higher molecular weight aromatic hydrocarbons in petroleum products requires preseparation to minimize interferences [9]. Also, GUMS is not orthogonal in the true physical sense and, hence, it has limited resolving power in the mass spectral dimension [3].…”

Abstract. Comprehensive two-dimensional gas chromatography is applicable to the analysis of complex petroleum mixtures. A kerosene sample analyzed by this method generates over six thousand chromatographic peaks. The chromatogram is orthogonal such that the second dimension separation is independent of the first. Aliphatics, aromatics, and naphthalene derivatives form distinct bands of peaks on the chromatographic plane with further subdivisions within each band based on chemical structure. With a nonpolar first column and a moderately polar second column, the first dimension separation is based largely on substance volatility while the second dimension separation is based on polarity. Each chromatographic peak has a pair of characteristic retention times, providing a more reliable identification. Peak capacity is much greater than that obtainable from any one-dimensional separation.

Key Words:Capillary GC Off-line LC preseparation Trace analysis Aromatic compounds in an n-alkane matrix SummaryThe possibilities and difficulties of trace analysis of highly complex organic mixtures has been demonstrated by the analysis of traces of numerous aromatic substances in an n-alkane matrix with a boiling point range of 151-270°C. Single column high resolution capillary gas chromatography (under optimized conditions) was performed after an off-line LC preseparation step which had been evaluated using a model mixture.Gas chromatographic quantitation of the 191 aromatic compounds identified was performed with an internal standard; following splitless injection and separation on a polydimethylsiloxane column under temperature-programmed conditions the compounds were detected by flame ionization. The response factors of aromatic hydrocarbons at trace levels were verified and the precision and reproducibility both of the GC determination and the overall analysis, including preseparation, were studied.Percentage by weight of individual aromatic compounds (mainly alkylbenzenes, indanes, naphthalenes, and acenaphthenes) was in the range lo9 to

The scope of the principal techniques employed for the analysis of hydrocarbon mixtures is discussed, with emphasis on the analysis of one and two ring aromatic compounds by single column capillary gas chromatography. The paper considers both the column and the selection of the temperature regime (isothermal and temperature programmed). Much space is devoted to the characterization of the compounds by means of retention data.
