## 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 holdโup time and pressure drop in both packed and open tubular columns. Predictions of both holdโup time and pressure d

## Abstract The influence of pressure drop on retention, selectivity, plate height and resolution was investigated systematically in packed supercritical fluid chromatography (SFC) using pure carbon dioxide as the mobile phase. Numerical methods developed previously which enabled the prediction of
## Abstract It is often observed that peak area precision in packed column supercritical fluid chromatography (pSFC) is rather poor when compared to values obtained in HPLC. Since the valves used for sample introduction in both techniques are identical, it is reasonable to expect that injection pre
