ChromaNik Sunrise C18-SAC Columns

Silanol Activity Controlled C18 Octadecyl R HPLC Columns

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.

A long chain C28 phase shows high steric selectivity and larger retention for fat-soluble compounds than a C18 phase.

Both C18-SAC and C28 phase can achieve unique separation which a conventional C18 cannot do.

Features of Sunrise C18-SAC

• The "2nd Choice" column which takes advantage of effective silanol groups interaction
• Reducing silanol groups with high adsorption activity
• The new separation mechanism including hydrogen bond and ion-exchange interaction
• Effective for separation of a basic compound and a polar compound
• Different selectivity and improvement of separation without changing a mobile phase
