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

Similar columns from other manufacturers to Ultisil XB-Phenyl

Specific columns from up to 10 families from other manufacturers with the same Mode and Modification. Compare a column to see its recorded specifications alongside this column.

How similarity is calculated
The percentage compares the two specific columns shown, using Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). Missing values are excluded. At least three criteria and 50% of the total weight must be available to show a score. Open Compare Column for every contribution and the calculation. Mode is a required discovery filter; length and internal diameter do not affect the score. Recommendations retain the family discovery rules. An eligible sponsor may appear first and is labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
