Silica Gel for Column Chromatography
Since conventional silica gels are weakly acidic, some pH sensitive compounds may be decomposed during the purification by column chromatography with the acidic silica gels. The pH of Silica Gel 60 (spherical neutral) is adjusted to nearly neutral for the separation of not only pH sensitive compounds but also new compounds that the physical properties are still unknown.
*All chromatograms shown below are obtained with silica gel packed into stainless and steel columns.
