ABSTRACT:
The invention includes a process for performing high performance liquid chromatography in the reverse phase. The present process for high performance separations by liquid chromatography uses a separations media, including separations packing materials for packed column separations, of polybutadiene coated and crosslinked on a surface of generally spherical metal oxide/hydroxide support particles comprising crystals of metal oxide/hydroxide with the crystals extending radially outward from a central core region and having a shape selected from principally acicular to principally lamellar. It has been found that liquid chromatography using the process of the present invention works particularly well in separating basic, nitrogen-containing compounds.
