Factors affecting the elution of elemental sulfur beyond the total permeation limit of a size-exclusion chromatographic (SEC) column are investigated. The pore diameter of the column packing is found to be the most important parameter, and optimum results are achieved from a single 10 3 pore polystyrene-divinylbenzene column with tetrahydrofuran as solvent. It is shown that both the column...
The hydrocarbon type analysis of light naphthas, alkylates and reformates was carried out by multidimensional gas chromatography (MD-g.c.) using a mode which provided the amounts and carbon number distributions of paraffins, olefins, naphthenes and aromatics (PONA) in each sample. The MD-g.c. results were compared with the total saturates, olefins and aromatics obtained by the ASTM method D 1319,...
