Abstract:

In recent years, comprehensive two-dimensional gas chromatography （GC×GC） have been
used widely, and the applications of this technique to many fields have already been reported. In
the standard method of oil analysis, the concentrations of aromatics and naphthalene hydrocarbons in
light petroleum products must be detected by more than two methods. Mono-aromatics, di-aromatics
etc. in light petroleum products were detected only by comprehensive two-dimensional gas
chromatography. After the proper selection of column system and optimization of chromatographic
conditions, the method can achieve the group separations of paraffins, olefins, naphthenes,
aromatics with 1 to 2 rings and some target components in light petroleum products with good
reproducibility and good precision. The recoveries of standard compounds were 89.5%-106.1%, and the
relative standard deviations of repeatedly detecting the components were all lower than 5.8%. It
took only 30 min to finish a determination.
