Monolithic chromatographic columns for HPLC based on divinylbenzene-styrene both with 1-vinylimidazole and with 4-vinylpyridine are prepared. The monoliths were synthesized in glass tubes with the inner diameter of 2 mm. Texture, hydrodynamic and chromatographic properties of the prepared columns were studied. Linear solvation energy relationships model was applied for the characterization of columns selectivity It is shown that changing the on 1-vinylimidazole or 4-vinylpyridine content in the initial solution allows to change the selectivity of the columns. An examples of small molecules and some proteins separations are presented.
