Ultisil XB-Phenyl

by Welch Materials

Ultisil XB Phenyl phase is less retentive than conventional C18 and C8 phases, but more retentive than standard cyano phase. Due to their ability to participate in π-π interactions, XB-Phenyl columns may actually more retentive than C18 or C8 columns towards certain polar aromatic compounds, depending on running conditions. The selectivity for highly polar aromatics, which are poorly retained on alkyl-bonded phases, combined with the reduced retentivity towards nonpolar compounds, makes XB-Phenyl an excellent choice for the analysis of complex mixtures of polar and non-polar analytes.

  • High surface coverage and exhaustive double end-capping
  • Excellent for aromatic, polar compounds and difficult pharmaceuticals
  • Different selectivity to XB-C18, XB-C8 and XB-CN
  • Exceptional batch-to-batch and column-to-column reproducibility
  • Available in dimensions from analytical to preparative for all sample sizes
Application areas:
Aromatic compounds Non-polar compounds Pharmaceutical molecules Polar compounds
