Popis: The contents of total aromatics and of mono-, di-, and polyaromatics in fuels may be rapidly and conveniently determined by supercritical fluid chromatography on capillary columns packed with silica using a supercritical carrier. The use of carbon dioxide mobile phase permits detection by flame ionisation. A study of the retention behaviour of test compounds allowed the separation temperature and pressure to be optimised. The aromatic content of a range of fuels (17–88%) determined in this way was in good agreement with fluorescent indicator analysis.
