Ultisil Phenyl-Ether
– 8 columnsPolar 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
