YMC-Pack Diol-NP Analytical HPLC Columns
In normal phase mode the YMC-Pack Diol stationary phase is a versatile alternative to silica. The bonded phase's hydroxyl groups provide good selectivity without excessive retention, since hydrogen bonding with the diol layer is not as strong as with the silanols on a non bonded silica surface. YMC Pack-Diol also provides improved reproducibility when compared with bare silica.
Diol packings are also suitable for separations using reversed phase techniques or molecular weight determination of proteins by gel filtration.
Features
- Suitable for normal phase, HILIC and SEC applications
- Good selectivity without excessive retention
- High product recovery rate
- Reproducible
- Improved peak shape versus bare silica
