Ultisil XB-C18

by Welch Materials

Ultisil XB-C18 columns, featuring high surface coverage and exhaustive endcapping, are an excellent choice as a general purpose C18 column for a wide variety of organic compounds. The bonding chemistry is optimized specifi cally for our base material. Our proprietary double end-capping leads to optimal performance with neutral, polar, acidic, basic, and chelating compounds.

  • The most universal C18 for most application
  • High surface area coverage and exhaustive endcapping
  • Excellent peak shape for polar compounds and strong bases
  • Exceptional batch-to-batch and column-to-column reproducibility
  • Available in dimensions from analytical to preparative for all sample sizes
Application areas:
Acidic compounds Basic compounds Chelating compounds Neutral compounds Polar compounds
