YMC-Pack Diol-NP is a versatile alternative to silica for normal-phase separations. The bonded layer’s-OH groups provide good selectivity without excessive retention, since hydrogen bonding with the Diol-NP layer is not as strong as one with the silanols on a bare silica surface. Diol-NP columns also provide better reproducibility when compared with bare silica columns.
