Polymer microparticles suitable for gel chromatography are formed by spraying a composition of a thermally-gelling polymer in an aqueous medium into ambient air and allowing the atomized composition to gel in the air. The gelled microparticles have a gel strength sufficient to preserve the structural integrity of the gelled microparticle upon collection thereof.
La présente invention concerne des microparticules de polymère se prêtant à la chromatographie sur gel. Pour former ces particules, on prend une composition de polymère se gélifiant thermiquement contenue dans un milieu aqueux, on la pulvérise dans l'air ambiant, et on laisse la composition atomiser se gélifier dans l'air. Ces microparticules gélifiées présentent une résistance du gel suffisante pour préserver l'intégrité structurelle de la microparticule gélifiée lorsqu'on la recueille.
