Gasochromatographic (GC) determination of sulfur compounds in diesel fuel with use of solid-phase
extraction on hyperbranched polystyrene with the subsequent fractional elution and gasochromatographic analysis
with frame-photometric detection is discussed. It is shown, that fractional elution on hyperbranched polystyrene
Purosep-200 leads to almost full removal of alkanes from sample of diesel, and of the using of ligand exchange
principles in the conditions during the solid-phase extraction on cationexchange MN-502, modified by silver
cations with the subsequent fractional elution allowes to separation substantially arenas and sulfur aromatic
compounds. On the basis of the obtained results the method of determination of sulfur compounds in the diesel
fuel is suggested
