Abstract:

Sulfur-containing compound types in diesel oil were characterized by comprehensive two-dimensional gas chromatography coupled with a sulfur chemiluminescence detector. Based on the retention values, orthogonal separation characteristics as well as the identification results of two-dimensional mass spectrum, the sulfur compounds were qualitatively identified. The mole response characteristics and linear response range of sulfur chemiluminescence detector were investigated. Using 4,6-dimethyl dibenzothiophene solution as external standard sample，the quantitative analysis on major sulfur compounds was established.

Key words: comprehensive two-dimensional gas chromatography, sulfur chemiluminescene detector, diesel oil, sulfur-containing compounds
