Abstract
Heavy polycyclic aromatic hydrocarbons (HPAHs) are analyzed using aromatic-selective size exclusion chromatography for the separation and quantitation of HPAHs. This method is suitable to determine the concentration of HPAHs in mixtures that include coronene and other HPAHs including 8 or more rings, such as contained in hydrocracker bottoms, or in pyrolysis oil or tar.
