Abstract
Method of chromatographically separating a mixture by contacting said mixture under chromatographic separation conditions with a chromatographic separation stationary phase comprising a polymer formed by coating substantially all of the surfaces of a microporous, comminuted substrate material with a monomer that is subsequently polymerized in situ with a cold-gas plasma discharge.
Claims7
Method of making a chromatographically active support material, said method comprising the steps of:
- coating the surfaces of a comminuted inorganic substrate material with a monomer selected from those monomers which, when polymerized, possess chromatographic properties;
- and
- exposing said monomer coated on said surface to an inert gas plasma for a time and of an intensity sufficient to induce polymerization of said monomer.
