The present invention is a method of producing a chromatographic separation matrix, wherein porous polymeric particles comprised of two layers with different properties are prepared in a two-phase system by (a) providing porous polymeric particles with reactive groups on their surfaces; (b) washing said particles with a first solvent and draining the particles to enclose a first phase; (c) wetting the outer layer of the particles by adding a second solvent, which is essentially insoluble in the first solvent; (d) reacting the reactive groups in the outer layer by adding a reagent, which is essentially non-reactive in the first solvent; and (e) coupling of chromatographic binding groups to the reactive groups in the inner layer. The invention also encompasses a porous polymer particle suitable for use as a chromatographic separation matrix and a process of separation, wherein a matrix according to the invention is used.

L'invention concerne un procédé de fabrication d'une matrice de séparation chromatographique dans lequel des particules de polymère poreux bicouches sont constituées d'un système diphase. Ce procédé consiste à : (a) doter les surfaces des particules de polymère poreux de groupes réactifs; (b) laver lesdites particules avec un premier solvant et les égoutter pour introduire une première phase; (c) humidifier la couche extérieure des particules en additionnant un second solvant, lequel est principalement insoluble dans le premier solvant; (d) faire réagir les groupes réactifs dans la couche extérieure en ajoutant un réactif, lequel est principalement insoluble dans le premier solvant; et enfin, (e) coupler les groupes de liaison chromatographique aux groupes réactifs dans la couche intérieure. Par ailleurs, l'invention concerne une particule de polymère poreux qui peut servir de matrice de séparation chromatographique ainsi qu'un procédé de séparation dans lequel une matrice est utilisée selon l'invention.
