supply over 30 kinds of silica g

desiccant in bags  ---Product list :

1) FNG Silica Gel: Spherical Sharp, used for air drying in the air separating process for various industrial gases.

2) C Type Silica Gel: Translucent Spherical Sharp, used for drier, adsorbent & catalyst carrier.

3) B Type Silica Gel: Transparent Spherical Sharp, mainly used as liquid adsorbents, Struture lying between macro-pored and fine-pored silica gel.

4) Blue Silica Gel: Lumps or Spherical Sharp, After absorbing Moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.

5) DL Blue Silica Gel: Lumps or Spherical Sharp, used as humidity indicator or drier in judging if the adsorption and drying process is up to the requirements.

6) Fine-Pored Silica Gel: Lumps or Spherical Sharp, used for drying and moisture-proof.

7) Macro-pored Silica Gel: Lumps or Spherical Sharp, used for moisture-proof packing and dehydration and purification of industrial gases.
8) Silica Gel (tablet): Used for moisture-proof for pharmaceutical and food industry.

9) Silica Gel for variable-pressure adsorption: Similar to fine-pored Silica gel, Its selective adsorptive capability is higher than fine-pored silica gel.

10) Silica gel for Column layer Chromatography: Since the amount of time, it takes to adsorb the various substance, it can achieve the separation and purification from the mixed components, used for refining petroleum and pharmaceutical industry.

11) Silica gel for thin layer Chromatography: Used for analysis and separation of various natural and synthetic substances.

12) Cat Sands(Cat litter): Used for pets, a ideal pet waste cleaner.

13) Silicic Acid: Used for fusion agent for processing tungsten filaments.

14) Silica Alumina Gel: Faint yellow molecular;
Formula: SiO2.Na2O3.mH2O; Used for dewatering of natural gas, adsorption and separation of light hydrocarbon.

15) Activated Silica G el: Used for identifying poisonous and harmful gases for atmospheric monitoring & mining industry.

Application :


silica gel is used in chromatography as a stationary phase. In column chromatography the stationary phase is most often composed of silica gel particles of 40-63 μm. Different particle sizes are used for achieving a desired separation of certain molecular sizes. In

this application, due to silica gel's polarity, non-polar components tend t o elute before more polar ones, hence the name normal phase chromatography. However, when hydrophobic groups (such as C18 groups) are attached to the silica gel then polar components elute first and the method is referred to as reverse phase chromatography. Silica gel is also applied to aluminum, glass, or plastic sheets for thin layer chromatography.

c.Cat litter

Silica gel is also used as cat litter by itself or in combination with more traditional materials, such as clays including bentonite. It is trackless and virtually odorless, albeit expensive.
