Sunniest series achieved the perfect end-capping through the development of their own method.
This column achieves high durability, under acidic and basic pH conditions, by the deactivation of residual silanol groups.
This series also includes UHPLC columns, for quick separations, which is the Sunniest C18-HT 2μm particle.
This special C18 reagent consists of the C18 chain part and the end-capping part like an arm which moves like a geometrid caterpillar so that a functional group on the tip of the arm can be bound to silanol groups at various positions on the silica surface.
After bonding this unique C18 reagent, an end-capping is densely done with trimethysilane (TMS) using the Silanol Activity Control (SAC) technique. The SAC technique was developed by Chromanik Technologies, Inc. for Sunrise C18. The SAC technique is an operation technique wherein silanol groups are converted into an asiloxane bond under high-temperature conditions.
