Prediction of retention behavior of ferrocene derivatives in supercritical fluid chromatography

The retention behavior in capillary supercritical fluid chromatography (SFC) of a range of ferrocene derivatives is demonstrated. Prediction of retention times and hence elution order of the ferrocene derivatives based on a knowledge of solute molar volume, solute solubility parameter and the physical parameters of the chromatography column system is shown to be feasible using this procedure.
