Description

BEH series columns are the latest generation of hybrid silica columns developed and launched. The hybrid silica combines the advantages of both organic and inorganic packing, with the high column efficiency, high mechanical strength and retention stability of pure silica packing, and the wide pH range stability and acidic inhibition of silanol groups of polymer packing, which can maintain a good column life even under extreme conditions.
1. Hybridised silica can reduce the surface silicone hydroxyl effect;
2. Significant reduction in bonding phase loss through triple bonding;
3. Excellent resistance to acids and bases (pH 1.0 -12.5) and good column life even under extreme conditions.
4. Double capping technology for maximum elimination of silicone hydroxyl residues.
5. Excellent selectivity and batch repeatability.
6. Pore sizes [ BOA, 200A and 300A] for applications ranging from small molecule analysis to large molecule biology Pharmaceutical applications
7. Acid and alkali tolerance
Good stability at low and high pH, pH=1.0 and pH= 12.5 mobile phases, with chromatographic performance remaining unchanged after 10 days of continuous flushing at high temperature conditions.
8. Batch repeatability
The homogeneous particle size of this hybrid silica, which has very high batch stability and reproducibility.
