Column Chromatography Silica Gel Manufacturers

This column chromatography silica gel is a high-purity porous adsorbent. It is widely used for the separation and purification of organic compounds. This product has excellent chemical stability, high specific surface area, and uniform pore size distribution. So, this silica gel is suitable for laboratory and industrial scale column chromatography separation. It can efficiently separate target components in complex mixtures.

Noted: We can custom silica gel desiccant for specific application.

Product Features and Advantages

1. Optimized pore structure provides a larger specific surface area. The high adsorption capacity ensures excellent separation performance.

2. Uniform particle size distribution. This column chromatography silica gel can achieve high-precision separation. Excellent resolution. Reduce tailing phenomenon.

3. Excellent chemical stability. Acid and alkali resistant. It is suitable for various organic solvent systems.

4. We offer different particle sizes (such as 40-63 μ m, 63-200 μ m, etc.) and pore sizes (such as 60 Å, 100 Å) , to meet different separation requirements.

5. Low heavy metal content. This column chromatography silica gel has undergone strict purification treatment. The impurity content is extremely low. Avoid interfering with sensitive samples.

Applications

Separation/Purification Type	Applicable Compounds
Polar Compound Separation	Alkaloids, sugars, phenols, organic acids
Nonpolar Compound Separation	Hydrocarbons, esters, terpenes
Isomer Separation	Cis-trans isomers, positional isomers (e.g., ortho/para-substituted aromatics)
Natural Product Purification	Plant extracts (flavonoids, saponins, alkaloids)
Organic Synthesis Intermediate Purification	Reaction mixtures, intermediates, catalyst residues
Chiral Compound Separation	Enantiomers/diastereomers (requires chiral-modified silica or additives)
Lipophilic Compound Separation	Fats, fat-soluble vitamins (A/D/E/K), steroids
Acid/Base/Neutral Separation	Mixed acidic, basic, and neutral compounds (e.g., amines, carboxylic acids)

Additional Notes

1. Inappropriate Situations

Strong acidic/alkaline compounds (which may cause dissolution or damage to silica gel)
Metal ions or inorganic salts (which need to be combined with other methods, such as ion exchange chromatography)
High molecular polymer, such as protein, polysaccharide (It needs gel filtration chromatography.)

2. Key Influencing Factors

Silica gel particle size (200-300 mesh is commonly used for atmospheric columns. Smaller particle sizes are used for pressurized columns.)
Mobile phase polarity (It needs to optimize the gradient elution scheme based on the polarity of the target substance.)
