Abstract
The contents of total aromatics and of mono-, di-, and polyaromatics i n fuels may be rapidly and conveniently determined by supercritical fl uid chromatography on capillary columns packed with silica using a sup ercritical carrier. The use of carbon dioxide mobile phase permits det ection by flame ionisation. A study of the retention behaviour of test compounds allowed the separation temperature and pressure to be optim ised. The aromatic content of a range of fuels (17-88%) determined in this way was in good agreement with fluorescent indicator analysis. (C ) 1998 Elsevier Science Ltd. All rights reserved.
