DESCRIPTION
Ultisil Polar RP is a polar embedded column in which a polar functional group is embedded in the carbon chain. The polar functional group close to the silica surface increases the wet ability of this phase, thus decreasing phase collapse, making this phase compatible with 100% water, even better than AQ-C18. The polar functional group 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.
