Abstract
In complex samples a reduction of the complexity of the sample is usually necessary before the quantification of polycyclic aromatic compounds (PAC) is undertaken. Here we report on an investigation on the use of low-boiling solvents for the traditional open-column chromatography on silica gel and alumina for minimizing evaporative losses of volatile aromatics. A color indicator capable of entering into charge-transfer interactions with the aromatic compounds with a concomitant color change was included to give a visual signal when the aromatics start eluting from the column.
