Unique Surface Chemistry of TYPE-C Silica Products
The surface of TYPE-C Silica is predominantly populated with non-polar, silicon-hydride (Si-H) groups instead
of the polar, silanol groups (Si-OH) that dominate the surface of previous varieties of silica. This feature of
TYPE-C Silica particles, gives it many unique, useful and helpful chromatographic qualities.
Some of the inherent limitations of Type-B silicas associated with free silanols have been overcome with TYPE-C
Silica products. These include but are not limited to;
- surface acidity
- improved pH stability
- less hydroscopic
as well as a unique separation character that allows for improved aqueous based reverse phase, organic solvent
based normal phase and aqueous based normal phase without an organic bonded stationary phase.
