Aluminium Oxide

Aluminum Oxide is a premium-quality adsorbent media that excels in column chromatography techniques. This aluminum oxide is typically amphoteric in nature, acting as a basic, acidic and neutral, providing the best results for chromatographers to separate various compounds.

It is a fine powder, also known as alumina oxide. Primarily, alumina acidic operations offer effective separation capabilities with mild acids, which can be improved using alkaline solvents.

The unique properties and characteristics of Al2O3 make it a special adsorbent for use in chromatographic separation. This active media is available in three different grades, each tailored to specific applications. The acidic, basic, and neutral grades are highly porous and sensitive to aromatic compounds, making them effective for separating sensitive materials.

Sorbchem India is the largest manufacturer of Aluminium Oxide for Chromatography, a reliable and efficient product for various chromatography applications, offering high-quality results and versatility in its usage.
