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

Similar columns from other manufacturers to Ultisil XB-C18

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
