The use of silica gel can be interpreted in two ways. It well know that silica (SiO2) can adsorb water on its surface. If you use silica dryed under 400 °C, the process of adsorption occurs by the silanol group. So, molecules with a polar groups like hydroxil, amine, nitrilic ... can make chemical interactions with the silica surface and can be retained more time into a column. In this case the adsorption is chemical. But, if you use a deactived silica (~5% H2O), the H2O molecules make a layer into a silica surface and the main process occurs by partition chromatography.
The silica gel colour is blue, and after capturing the moisture the colour is become a pink colour.
You cannot eat Silica Gel because it is not food. Silica Gel is a non-toxic substance that is used to absorb moisture. The reason packets of Silica Gel are labeled "Do Not Eat" is because they pose a choking hazard.
If dry, silica gel is almost pure silicon dioxide, SiO2.
Probably you just seal the tank which contains the silica gel. The idea is that you prevent silica gel from coming in contact with the air
It is a column chromatography grade silica gel.
Column Chromatography is best choice for if you are looking for Silica Gel TLC Plates for Column Chromatography. For more inquiry call on 9879203377.

Property of Silica gel is to absorb the moisture. Colour of dry silica gel is blue and it turns into pink when it is saturated with moisture. When the colour of silica gel turns out pink, the wet silica gel is removed and the fresh silica gel is filled. The wet silica gel can be heated and made dry for reuse.
I get Silica Gel at that place of Silica Gel Supplier where Silica Gel Desiccant is DMF Free and USFDA Approved, because high Humidity removal and more moisture absorber is only Silica Gel beads and crystals.
The main use for Silica gel is to control humidity. It is often used in packaging to prevent damage or spoilage of products being shipped.
Silica gel is blue in colour. When the silica gel has soaked up a lot of moisture, the silica gel turns to pink. Once the silica gel turns pink it cannot adsorb any more moisture. It needs to be regenerated. This can be accomplished by heating it in an oven. The heat expels the moisture, the silica gel turns blue and becomes reusable
Silica gel packets are dessicants. These packets adsorb moisture and prevent damage to stored valuables and supplies. Silica gel is silicon dioxide, SiO2, like sand on the beach. Inside each small silica gel granule is a network of inter-connecting microscopic pores, which attract and hold moisture by a phenomena known as adsorption. Silica gel is packaged in a fibrous material that is capable of withstanding normal handling and be able to breathe. This means that water molecules can pass through the material and be adsorbed by the silica gel. Ready to use silica gel is blue in colour.
