Abstract Information :

Complex sample mixtures, such as petroleum hydrocarbon fractions, require a detailed separation of the individual organic compound types. A traditional GC approach will lead to multiple coelutions, however in this present work a 2D GC approach was utilized to explore the multi-dimensional separation of complex light and heavier hydrocarbons. Using a 2D GC, the complex hydrocarbon mixture can be thoroughly resolved due to the combination of the high peak capacity in 2D GC, along with the orthogonal selectivity of the Zebron GC columns that provide a complementary selectivity in two dimensions. This complete resolution includes a range of compounds, for example linear alkanes (paraffins), linear alkenes (olefins), cyclic alkanes, aromatics (one - tetralin ring derivatives), aromatics (one, two, three, four, and five - benzene ring derivatives). The combination of Zebron ZB-1HT Inferno with ZB-35HT Inferno provides a high temperature capability to further elute all the fractions, and to provide a targeted selectivity that separates individual aliphatic and aromatic analytes from each other.
