Abstract
The chromatography of polycyclic hydrocarbons from air samples is a combination of science and art. The art is to achieve the best usable separations in the shortest working time. This involves compromises including the activity of the alumina, the depth of the adsorbent and the amount of ether, or other polar solvent used. Ultraviolet spectroscopy as a monitoring technique is not sufficiently sensitive. This lack of sensitivity may be the reason that column losses have been reported. Fluorescence as a monitoring technique is much more sensitive and must be used when benzo[ a]pyrene is being measured, since the benzo[ k]fluoranthene present in the benzo[ a]pyrene fractions causes serious interference with measurements made at the characteristic benzo[ a]pyrene peak at ca. 402 nm.
