The dependence of the capacity factor of polycyclic aromatic hydrocarbons on column temperature and on the density of the mobile phase in supercritical-fluid chromatography was investigated using carbon dioxide as the mobile phase. Logarithmic capacity factors of polycyclic aromatic hydrocarbons were obtained as a linear function of the reciprocal column temperature at a constant molar volume of carbon dioxide.
The application of the Retention Prediction System to supercritical-fluid chromatography is demonstrated: one can predict the retention of polycyclic aromatic hydrocarbons using equations including column temperature, density and the physico-chemical properties of the solutes as the parameters.
