Aluminium Oxide for Chromatography
Product description
Aluminium Oxide (Al₂O₃) is a high-performance adsorbent widely used in column chromatography for the separation and purification of compounds. Naturally amphoteric in nature, it is available in acidic, basic, and neutral grades, allowing chromatographers to choose the optimal medium for their specific application.
Available as a fine, highly porous powder, aluminium oxide delivers excellent separation efficiency. Acidic alumina is ideal for operations involving mild acids, while basic alumina works effectively with alkaline solvents. Neutral alumina offers balanced performance for a wide range of compounds, particularly those sensitive to aromatic interactions.
With its unique adsorptive properties and versatility, aluminium oxide is an essential medium for the effective separation of sensitive and complex materials. Silchem Pharma is a leading manufacturer of premium-quality aluminium oxide for chromatography, ensuring consistent performance, reliability, and purity across various industrial and research applications.
