Sorbent Technologies offers a complete selection of aluminum oxide (alumina) products for column chromatography. All of these products are standardized according to Brockmann methods to ensure quality and reproducibility. Aluminas are ideal for natural product extraction, purification & decolorization, heavy metal removal, cleanup, and more.
Â
We offer the best selection of standadrdize aluminas with defined activities, pH values (acid, base, neutral), and particle distributions (MPLC, Flash, Gravity). All of our aluminas are manufactured using GMP standards ensuring the highest performance and lot-to-lot reproducibility with no scale-up limitations. Â
Our selection includes Aluminas for:
- Standard Chromatographic Techniques:Â Flash Chromatography, Classic Column Chromatography, MPLC, HPLC, TLC, and DCC.
- Special Techniques:  Removal of Peroxides from Solvents, Purification of Solvents for UV-Spectroscopy, Natural Product Purification and Decolorization, Heavy Metals Removal, Clean-up, Dioxin analysis, and Technique of Isotopes.
- Custom Aluminas:Â Modifiable porosities, surface area, and particle distributions, Colloidals. Â Inquire.
