Ultisil XB-Diol

by Welch Materials

For normal-phase chromatography, the Ultisil product line offers new Diol bonded silica packing materials. Ultisil XB-Diol may also be used as a polar sorbent in normal phase. Like bare silica, Ultisil XB-Diol has the ability to form hydrogen bonds and has the capacity to separate structure isomers.

  • More stable than the traditional normal phase columns, such as Silica, Amine
  • Could be used in reverse phase analysis
  • Similar polarity to Amine
  • Good selectivity without excessive retention
  • Improved peak shape versus bare silica
