Abstract

Polymyxin antibiotics were separated by using reversed-phase chromatography in the displacement mode with columns generally employed in analytical separations. By using an aqueous solution of dodecyloctyldimethylammonium chloride as the displacer more than 100 mg of commercial polymyxin B sulfate could be separated into its constituents on a 250 × 4.6 mm column packed with 5-μm octyl-silica. The results are compared to those obtained by elution chromatography and some of the main features of displacement chromatography are discussed.
