More about Reagent Column Chromatography Silica Gel This type of silica gel is made of colloidal particles with condensate structure. The colloidal particle is the polycondensate of hydrated silica gel, belonging to non-crystalline-state substance. The interspaces of aggregation of colloidal particles form micro porous structure inside the reagent column chromatography silica gel particle. All this makes the silica gel a superior adsorption material with high specific surface area, high purity and high activity.
As the absorption performance of reagent column chromatography silica gel depends on the micro porous structure and inner pore surface formed during the production of silica gel material. Hence, careful selection of wide pore block silica gel is very important. Recommended specifications of wide pore silica gel include: adsorption capacity 80±2%, specific surface area 360m2/g, average pore diameter 9nm (90 Angstrom). In addition to raw material selection, several procedures are also involved in processing the silica gel, including crushing raw material, classifying particle size, acid treatment, washing with purified water, drying, packing and testing.
