Abstract

Disclosed is a medium for chromatography in which a body of material which is inherently hydrophobic is modified at its surface region by chemical reactions which change the chemical composition in the surface region to one whose exposed surface is hydrophilic, is integral with the core of the material, and is derivatizable.
