Welch Materials Ultisil XB-CN Columns

Ultisil XB-CN column is suitable for highly hydrophobic samples and compounds that cannot be eluted on conventional reversed-phase columns. In normal-phase chromatography, the cyano-bonded phase can serve as an alternative to silica, offering faster equilibration and more consistent surface activity compared to non-derivatized silica.

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

  • Ultra-pure spherical porous silica, purity > 99.999%
  • Wide pH range: 2.0-8.0
  • High efficiency: theoretical plate > 80000/m
  • Excellent peak symmetry: tailing factor=0.95~1.05
  • Exceptional lot-to-lot reproducibility
