Patent

CA 2541284

The invention relates to a method for producing monolithic molded elements e.g. as sorbents for chromatographic columns or capillary vessels. The aim of the invention is for said molded elements to be able to remain directly in the gel mold thereof following the production process. Said aim is achieved by the inventive method, according to which the surface of the gel mold is activated by etching, increasing the surface, or chemically modifying the surface before the gelling mold is filled with the monomer sol.

L'invention concerne un procédé servant à produire des corps moulés monolithiques, par exemple en tant que sorbants pour des colonnes de chromatographie ou des capillaires, les corps moulés pouvant rester directement dans leur moule de gélification après la production. Selon le procédé de l'invention, la surface du moule de gélification est activée, avant le remplissage du moule avec le sol monomérique, par attaque, accroissement de la surface ou modification chimique de la surface.
