ABSTRACT:
An apparatus and a method for size exclusion chromatography is provided. The apparatus is a chromatographic column adapted for use in size exclusion chromatography by having dimensions suitable for size exclusion chromatography and by having a packing material comprising generally spherical particles having wedge-shaped macropores. Preferred particles are in the shape of lamellar and/or acicular crystals extending radially outwardly from a central core region and comprise aluminum oxide, aluminum hydroxide or a mixture thereof. The method involves passing a solution of macromolecules through a column adapted for size exclusion chromatography packed with such particles. The particles effectively and efficiently separate a wide range of macromolecules in decreasing order of their molecular weight.
