Welch Materials Ultisil Alk C18 Columns

Ultisil Alk C18 column features a mixed stationary phase with hydrophobic and electrostatic interactions, along with HILIC properties. It allows for rapid separation of similar samples by adjusting the mobile phase.

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
