Orthogonal Selectivity for Separation of Oxygenated Compounds and Hydrocarbons in Alternative Fuels by Two-Dimensional Gas Chromatography

Abstract:

This study showed that compared to conventional configurations, a re-versed configuration involving a highly polar column in the first dimension and a non-polar one in the second enables the separation of oxygenates and hydrocarbons in one single run. In fact, the 2D contour plots obtained under these conditions exhibit good resolution and high space occupation. Nevertheless, in the future there is still an opportunity to separate nitroge-nates from oxygenates for improved quantification. Further study is needed to accomplish this, by utilizing either sample preparation or online fraction-ation in a multi-technical analytical approach with multidimensional gas chromatography.
