Ultisil Phenyl-Ether

by Welch Materials

Polar embedded phases have been developed for more than 10 years. The earlier development of polar embedded phase is on amide phase. The polar functional group close to the surface increases the wettability of phase, thus decreasing phase collapse, so that up to 95% water phase could be applied in the mobile phase. It also shields the effects of unreacted silanol groups, providing excellent peak shape for very polar and strong basic compounds and different selectivity than C18 phase. We provide two kinds of packing materials - Ultisil Polar-RP and Ultisil Phenyl-Ether.

Ultisil Phenyl-Ether:

  • Improved polar & aromatic reversed phases selectivity that complements the more conventional C18 column chemistries
  • Better selectivity than phenyl phase for separation of nitrobenzene isomers
  • Improved peak shape of the highly acidic polar compound, and an alternative selectivity compared to other polar phases such as polar embedded phase
  • Compatible with 100% water mobile phase

Similar columns from other manufacturers to Ultisil Phenyl-Ether

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.
No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
