摘要：

A supercritical fluid chromatographic system was constructed to provide separations and fraction collection on a semipreparative scale. Columns packed with silica materials of intermediate particle sizes (30-70 mu m) were used to allow dynamic pressure programming with minimum pressure drop of the CO//2 mobile phase along the length of the column. A variety of complex coal- and petroleum-derived polycyclic aromatic compound mixtures were fractionated according to the number of aromatic rings using columns packed with an NH//2-modified stationary phase bonded on silica particles.
