A comparative analysis of gasoline samples has been performed using several chromatographic methods: one-dimensional detailed hydrocarbon analysis (DHA), which allows for determination of the individual component composition of a liquid petroleum product with identification by retention times; two-dimensional gas chromatography 2D-GC with identification by retention times; two-dimensional gas chromatography 2D-GC-MS with identification by retention times and mass spectra of compounds; and determination of the group composition of gasoline by multidimensional gas chromatography using traps and a reactor with a flame-ionization detector. The advantages and disadvantages of each procedure have been shown and application areas for each method have been specified.
