Column chromatography silica gel is white powder, the main component is SiO₂·nH₂O, insoluble in water, inorganic acid and other organic solvents, soluble in HF and concentrated caustic soda solution. It absorbs moisture in the air.Because of the difference in adsorption and retention time of different substances, various substances can be separated and purified.

The medicinal silica gel desiccant conforms to the standard of YBB00122005"Medicinal silica gel desiccant in solid paper bags". The medicinal desiccant is filled with silica gel. According to the weight is divided into 0.5g, 1g, 2g, 3g, 5g, 10g, 20g, 50g, etc., can be processed into various specifications according to customer requirements. According to the shape is divided into:bag, roll, etc. Packaging materials: composite paper, tea paper, OPP, Aihua paper, Dupont paper, etc.

The main raw materials of industrial desiccant are: narrow pore silica gel, B-type silica gel, color-changing silica gel,active mineral balls, montmorillonite, molecular sieve and so on. Users can choose according to the type characteristics of packaging products.

Calcium chloride desiccant is a commonly used humidity-absorbing material, primarily used to adsorb moisture in the air and reduce humidity. Its main principles are as follows:
1. Hygroscopic Reaction: Calcium chloride has strong hydrophilicity. When exposed to humid air, it absorbs moisture from the surrounding environment through a hygroscopic reaction. This occurs because calcium chloride's structure contains hydrates that form compounds with environmental moisture, thereby adsorbing water.
2. Moisture Absorption Capaciy: As a desiccant, calcium chloride has high moisture absorption capacity and can continuously absorb humidity from the air until it reaches saturation.

Type A silica gel also known as Narrow pore silica gel, is transparent and translucent particles. It is divided into two types: spherical and block. The main component is SiO₂·nH₂O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and concentrated caustic soda solution. High mechanical strength, good wear resistance.The pore volume is 0.35-0.5ml/g, pore size 20-40Å, specific surface area ≥600㎡/g.

Blue silica gel has the adsorption and moisture-proof effect of narrow pore silica gel, It is characterized by the moisture absorption process, it can become light blue with the increase of moisture absorption, and finally become light red or light pink. It can indicate the humidity of the environment and also visually show whether a new desiccant needs to be replaced.

FNG water-resistant silica gel is white or off-white multi-microporous particles, the main component is SiO₂·nH₂O, Insoluble in water and inorganic acids, soluble in hydrofluoric acid and concentrated caustic soda solutions. High mechanical strength. The product is made of general silica gel as raw material after further processing of heterogeneous shaped silica gel, it has the pore structure and adsorption properties of ordinary homogeneous silica gel at the same time also has good water resistance, that is, it does not burst in water, thus expanding the application field of silica gel.

The coarse pore microsphere silica gel is a milky white particle, the main component is SiO₂·nH₂O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and concentrated caustic soda solution. The pore volume is 0.80-1.30ml/g, pore size 80-120Å, specific surface area 300-550㎡/g.

Flower desiccant is a microporous silica material, that is safe, odorless, and has stable chemical properties. It exhibits excellent hygroscopic capacity. Combine with blue indicating silica gel or orange indicating silica gel, it smoisture absorption is visible, allowing for intuitive judgment of the drying state of flowers. Additionally, it is reusable.
Using this desiccant shortens the drying period for flowers and effectively maintains the original color and shape of the petals. After drying, the flowers or bouquets should be stored in a dry environment to prevent moisture absorption.

Silica gel decolorizing sand is produced from macroporous silica gel as raw material, with SiO₂ as the main component. It has stable chemical properties and does not react with other acids or base except concentrated caustic alkali solutions and hydrofluoric acid.
