Welch Materials Ultisil Diol Columns

Ultisil Diol is a normal-phase column offering superior stability and reproducibility compared to silica and amino columns, as well as enhanced selectivity and peak shape. Its unique bonding technology ensures stable stationary phase structure, while strict manufacturing processes guarantee excellent batch-to-batch reproducibility.

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
