SinoPak BEH AQ-C18

SinoPak®BEH Series This hybrid silica packing combines the advantages of both organic and inorganic materials, delivering the high column efficiency, high mechanical strength, and stable retention characteristics of pure silica, alongside the broad pH stability and reduced acidic silanol activity of polymer-based packings. Even under extreme conditions, it maintains excellent column longevity.

The hybrid silica packing reduces surface silanol effects:

Bonding via triazole linkage significantly minimizes phase loss.
Excellent acid and alkali resistance (pH 1.0-12.5), ensuring strong column durability even under harsh conditions.
Dual end-capping technology thoroughly eliminates residual silanols.
Provides superior selectivity and excellent batch-to-batch reproducibility.
