Adsorbents Used in Column Chromatography

1. Adsorbents Used in Column Chromatography Silica gel and Aluminium Oxide are commonly Adsorbents Used in Column Chromatography. Swambe Chemicals provides two types of silica gel crystals. Silica Gel Crystals Silica Gel Blue Crystals: Silica gel is well popular adsorbent used for controlling the moisture in range of industries and applications. The main purpose of using silica gel is to prevent the moisture and humidity to damage the products and equipment. It is considered as the most effective way to keep the level of moisture moderate, so that it cannot affect the packaging products and other applications. It is also known as the indicating silica gel and blue desiccants. The range of particle crystals size include 1-3 mesh, 3-4 mesh, 3-8 mesh, 5-8, 9-16 mesh etc. The most suitable mesh size is used based on the application as well as the quantity of the products.

2. Silica Gel White Crystals: White silica gel in crystal form is an active adsorbent that can adsorb moisture from gases and liquids. This type of silica gel in granular or beaded form is used in many industries where there is a need of desiccant or adsorbent with high moisture adsorption capacity. It offers non-toxic and non-corrosive moisture controlling solution that can be used for protecting and preserving the products with great effectiveness. The colour of silica gel white crystals turns into milky or hazy white when it adsorbs as much moisture as it can. This silica gel has higher capacity to adsorb moisture as compared to indicating silica gel. The most suitable mesh size needs to be selected based on the application. It can be used in pharmaceutical, petrochemical, fertilizer plants, dehumidification process, optical instruments, drying of air & gases and several other industries and their relevant applications. Aluminium Oxide Aluminium Oxide for Chromatography is a white to off-white, fine- grained powder, highly porous form of aluminium oxide. Its surface is more polar than that of Silica Gel and, reflecting the amphoteric of aluminium, has both acidic and essential characteristics. The chromatographic characteristics are determined by its specific (internal)

3. surface area measured by the BET method, which means pore diameter and pore volume. The latter two concern the specific surface area. Aluminium Oxide for chromatography is being used in the laboratory and industrial production. For more information, just visit our website at https://www.swambe.com or just contact us on 9879203377.
