Abstract

UN MATERIAL CROMATOGRAFICO QUE CONTIENE MEJORAS EN LA RESISTENCIA AL CHOQUE Y UN ALTO NIVEL DE GRUPOS DE SILANOL DE SUPERFICIE. COMPRENDE MICROESFERAS DE SILICE POROSO QUE TIENEN UN DIAMETRO MEDIO DE 0,5 A 35 MICRAS LAS CUALES COMPRENDEN UNA PLURALIDAD DE PARTICULAS COLOIDALES UNIFORMES DE TAMAÑO CON UNA SUPERFICIE DE SILICE DISTRIBUIDAS EN UN ENREJADO TRIDIMENSIONAL INTERCONECTADO; OCUPANDO LAS PARTICULAS COLOIDALES MENOS DE 50% DE VOLUMENES DE LAS MICROESFERAS CON EL VOLUMEN RESTANTE OCUPADO POR POROS INTERCONECTADOS QUE TIENEN UNA UNIFORME DISTRIBUCION DEL TAMAÑO DE LOS MISMOS; LAS MICROESFERAS TIENEN UNA TOTAL CONCENTRACION DE GRUPOS DE SILANOL, ENTRE 6 Y 16 MICROMOLES POR METRO CUADRADO. EL MATERIAL PUEDE REACCIONAR CON UN AGENTE SILANIZADO PARA GENERAR UNA SUPERFICIE COMPLETAMENTE SILANIZADA.
