Silanol Activity Controlled C28 Column

Sunrise columns are very unique. Silanol Activity Control (SAC) technology leads not only adding an interaction by silanol groups but also a symmetrical peak forbasic compounds.

In general, the silanol group remaining in the silica-based stationary phase in such as C18 (ODS) has been the cause of adsorption and peak tailing of a basic compound. Because silanol groups in proximity to the hydrophobic group is poorly hydrated, it indicates a high adsorption properties.

For reducing the effect of the residual silanol groups, a variety of end-capping techniques have been developed.

The C28 chain improves separation of fat-soluble compounds in comparison with C18 phases and gives excellent reproducibility of the retention under highly aqueous conditions. Different selectivity.

SAC (silanol activity control) technology

ChromaNik developed the SAC technology that only silanol groups with high absorption activity were selectively reduced and richly hydrated silanol groups without high absorption activity remained.

This technology allowed that a basic compound was separated without any peak tailing. Furthermore, not only hydrophobic interaction but also hydrogen bonding capacity and ion exchange interaction by richly hydrated silanol groups worked on reversed phase separation.
