摘要：
The retention behavior of polycyclic aromatic hydrocarbons (PAHs) in packed-column supercritical fluid chromatography (SFC) is studied for monomeric and polymeric C(1)8 columns, Molecular shape discrimination (shape selectivity) is assessed through the use of Standard Reference Materials (SRMs), and changes in selectivity are studied as a function of temperature, pressure, and mobile phase composition, Examples of separations of complex PAH isomer mixtures are presented, and guidelines are provided for modification and optimization of shape selectivity in SFC.
