Welch Materials Ultisil XB-Phenyl Columns

Ultisil XB-Phenyl column features a unique stationary phase bonding and double endcapping technology, ensuring superior peak symmetry. It offers distinct selectivity compared to straight-chain alkane, providing excellent separation for aromatic and polar compounds. It serves as an ideal replacement for most phenylpropyl-bonded silica columns on the market, with low UV and MS bleed.

Ultisil Series HPLC Columns are based on ultra-pure (purity > 99.999%) spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil column is the best choice for method development. owing to complete bonding chemistries and stable performance.

Features
