Abstract:
This paper is dedicated to the development of the method of high-temperature two-dimensional gas chromatography (HT-GC × GC) using a flow modulator for the analysis of a number of complex high-boiling samples. A method has been developed that allows to analyze complex samples with a temperature up to 360 °C using a combination of non-polar and mid-polar columns. We have achieved separations of such complex mixtures as products of thermal cracking of slack wax, vacuum gas oil (VGO) and the products of its processing, a product of catalytic processing of sludge sediments pyrolysate and products of polyethylene pyrolysis. The method makes it possible to achieve good resolution in the previously listed samples between the groups of aromatic and aliphatic hydrocarbons. In addition, the group of aliphatic hydrocarbons was resolved into separate constituent classes: alkanes, alkenes, alkadienes, and cycloalkanes. A good resolution was reached for sludge pyrolysis samples between the groups of polar compounds and aromatic and aliphatic hydrocarbons. Comparisons with other standardized methods illustrate the high potential of high-temperature two-dimensional gas chromatography for the analysis of high-boiling mixtures.
