Ultisil XB-Diol
– 69 columns
Vendor: Welch Materials
For normal-phase chromatography, the Ultisil product line offers new Diol bonded silica packing materials. Ultisil XB-Diol may also be used as a polar sorbent in normal phase. Like bare silica, Ultisil XB-Diol has the ability to form hydrogen bonds and has the capacity to separate structure isomers.
- More stable than the traditional normal phase columns, such as Silica, Amine
- Could be used in reverse phase analysis
- Similar polarity to Amine
- Good selectivity without excessive retention
- Improved peak shape versus bare silica
