Currently, the selection of a hydrophobic interaction chromatography (HIC) sorbent for protein separation purposes is entirely based on empirical means. An attempt was made to characterize different HIC sorbents from various manufacturers. The selectivity was determined by isocratic pulse experiments of a set of reference proteins and an algorithm was developed to classify the sorbents according to their selectivity and hydrophobicity. The obtained semi-quantitative parameters take into account the dependence of salt on adsorption. The sorbent characteristics evaluated with the model proteins were compared to the separation of a real feedstock. A good agreement was achieved between the developed evaluation procedure and the separation behaviour of the real feed stock.
