SinoPak BEH Phenyl-Hexyl

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.

  • Column: SinoPak BEH Phenyl-Hexyl, 5 μm, 4.6 mm × 150 mm
  • Mobile phase: Water
  • Flow rate: 1.5 mL/min
  • Detection: RID
  • Injection volume: 10 μL

How It Works

Phenyl-hexyl silane bonded ethylene bridge hybridized silica gel, with excellent chemical stability. Triple bonding, low loss of phenyl groups, double tailing technology, can obtain good peak shape. It offers selectivity distinct from that of straight-chain alkane chromatographic columns such as C18 or C8, making it suitable for the analysis of aromatic and amine compounds.
