NOVELTY – The production of high-efficiency liquid chromatography stationary phases involves adsorption and immobilization of polysiloxanes in the pores of porous silica. USE – As liquid chromatography phase. ADVANTAGE – The resulting phases are comparatively inexpensive and easy to use, relative to the conventional ”combined” stationary phases.
