Abstract

CETTE INVENTION CONCERNE LES COLONNES CAPILLAIRES POUR CHROMATOGRAPHIE EN PHASE GAZEUSE. LA COLONNE SUIVANT L'INVENTION EST CONSTITUEE PAR UN NOYAU MUNI D'UN OU PLUSIEURS SILLONS HELICOIDAUX ET ENTOURE DE FACON ETANCHE PAR UNE GAINE TUBULAIRE. LA DIMENSION DU OU DES SILLONS EST TELLE QU'IL EN RESULTE, AVEC LA PAROI INTERIEURE DE LA GAINE TUBULAIRE, LA FORMATION D'UN PASSAGE CAPILLAIRE QUI S'ETEND SELON UN PROFIL HELICOIDAL TOUT AUTOUR DU NOYAU. LA PHASE STATIONNAIRE EST DEPOSEE SUR LES PAROIS DU OU DES SILLONS DU NOYAU OU BIEN SUR LA PAROI INTERIEURE DE LA GAINE TUBULAIRE AVANT LEUR ASSEMBLAGE, PAR EXEMPLE PAR IMMERSION DU NOYAU DANS UNE MATIERE APPROPRIEE ET SECHAGE. L'ASSEMBLAGE S'EFFECTUE EN RESSERRANT PAR UN MOYEN QUELCONQUE LA GAINE TUBULAIRE AUTOUR DU NOYAU POUR REALISER L'ETANCHEITE DU PASSAGE CAPILLAIRE. UNE COLONNE DE CE TYPE PEUT ETRE REALISEE DE MANIERE NETTEMENT PLUS RAPIDE ET PLUS SIMPLE QUE LES COLONNES CAPILLAIRES EXISTANTES.
