## Abstract The effects of the pressure drop across the column on retention and efficiency in SFC have been studied. Numerical methods are described which enable the prediction of hold‐up time and pressure drop in both packed and open tubular columns. Predictions of both hold‐up time and pressure d
Calculations have been carried out of the average densities and capacity factors in supercritical fluid chromatographic (SFC) columns, taking into account the effect of the pressure drop along the column using, as examples, carbon dioxide as the mobile phase and phenanthrene as the solute. The value
