Column Chromatography Silica Gel

Sinchemcolumn chromatography silica is made from superior quality silica gel. Its maincharacteristic is that this product can realize separation and purification bythe difference in adsorption and retaining time for different ingredients.

Advantages
1. Rigid structure andhigh strength enable Sinchem column chromatography silica gel to withstand upto 30MPa high pressure.
2. With superior absorptionperformance, the silica gel can be used to separate ingredients with similarstructure, characteristics or even isomer.
3. It has good thermal stability andchemical stability.
4. Silica gel is a solid gel based onSiO2 and features compact structure. Therefore, it will not pollute the targetproduct because no organic matter can run off in process of application.
5.Available in a wide range of average pore diameters, Sinchem columnchromatography silica gel can be used for separation and purification of thesubstances with different characteristics, molecular weight and molecularstructure.

Types
1. Wide pore column chromatography silica gel, which can be further dividedinto industrial grade wide pore column chromatography silica gel and reagentgrade column chromatography silica gel
2.Narrow pore column chromatography silica gel

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

Usage
Reagentcolumn chromatography silica gel is used in a variety of applications.
1.Used for separation and extraction of Chinese herb medicine, chemical synthesispharmaceuticals and biological active substance.
2.Used for extraction of biological active substances such as polypeptide ofmacromolecule protein during fermentation process and also used for acidengineering technology
3.Suitable for preparation of highly-purified substances through adsorption andseparation of column chromatography silica gel
4.Ideal for dehydration and refining of organic substance
5.Used for removal of harmful ingredients from edible vegetable oil
6.Fit for refining of petroleum products
