Multi-Mode Separation Sunrise C18 and C18-SAC Silanol Activity Controlled C18

Sunrise C18

• Fully end--capped C18 column

• Full end-capping after silanol activity control

• Reducing adsorption of an extremely basic compound

•  A good peak shape for metal chelating compounds

•  Widely available for general reversed-phase separations

Sunrise C18-SAC

• Takes advantage of effective silanol interaction

• Reducing silanol groups with high active 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

Multi- mode separation is achieved on Sunrise Series (pg. 4 of Catalog)

• Sunrise C18-SAC is bonded with octadecylsilane on  pure silica gel and controls its silanol activity without end-capping.
• Its carbon content is 14%.
• Separation on Sunrise C18-SAC is done including hydrogen bond and ion-exchange interaction based on silanol groups except for hydrophobic interaction.
• Control of pH and salt concentration of a mobile phase regulates retention.
