Caprisil C8-P 5μm 100A Prep Column

Caprisil C8 - P is specially deactivated to produce superior peak shapes for amines and acids. Caprisil C8 - P superior performance is the result of a multistep process beginning with ultra-pure synthetically produced spherical silica. The ultra-pure silica particles are then fully hydroxylated before they undergo an extensive bonding monomeric C8 alkyl chains, using proprietary bonding procedures. The bonded particles are then exhaustively endcapped to react any remaining silanol groups yielding columns that are much more resistant to degradation by acidic and basic mobile phase compositions, while improving peak shapes for amines and acids.

C8-P columns are designed with advanced surface treatment technology to deliver excellent performance for routine and complex analyses.

By adopting a double end-capping process, these columns effectively mask residual silanol groups on the silica surface, minimizing secondary interactions and ensuring sharper, more symmetrical peak shapes.

The ultra-high-density bonding technology extends the usable pH range from 1.5 to 10, making these columns highly durable and particularly effective for the separation of strong alkaline compounds and complex mixtures, such as traditional Chinese medicine components.
