Reversed-Phase Silica, PBB

• Product Overview: Reversed-phase chromatography silica gel features highly uniform particle size, narrow pore size distribution, high mechanical strength, high bonding density, and favorable end-capping. These properties deliver robust physical and chemical performance including easy column packing, high column efficiency, high resolution, low back pressure, and wide pH tolerance, with minimal bonded phase bleed. The result is high loading capacity, favorable selectivity, good resolution, high efficiency, long column lifetime, and low purification cost.
  The comprehensive product range meets the requirements of both analytical UPLC/HPLC and preparative HPLC (Prep-HPLC), and is widely used for chromatographic analysis and industrial production of organic compounds, natural products, fermentation and semi-synthetic antibiotics, and protein macromolecules.
  Available bonded phases include C1, C4, C8, C18, C18 AQ, C18 Polar, C30, Phenyl, and others, to meet reversed-phase analysis and preparative separation needs for various sample types. Custom products available for specialized applications.
• Matrix: High-purity silica
• Average particle size: 10 µm
• Pore Size (Å): 120
• Surface area: ~310 m²/g
• Ligand: Pentabromophenyl (PBB)
• % Carbon: 8%
• pH working range: 2–8
• Bulk density: ~0.50 g/mL
• Product features: Bromine atoms possess large dispersive forces, enabling separation based on dispersion force differences. The pentabromophenyl bonded phase is therefore suitable for separation and purification of longer-chain, higher-molecular-weight compounds, compounds with larger functional group atoms (such as halogens), and compounds with highly mobile electron density (such as aromatic compounds).
