A Normal Phase Silica Alternative

The YMC Diol-NP stationary phase 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.

High Product Recovery

Like all YMC silica-based bonded phase,
the Diol-NP phase starts with an underlying silica support of exceptional purity.
YMC manufacturing and quality assurance possession ensure that the silica has a very low metal content. The silica purity greatly reduces nonspecific sample adsorption. As a result, you can expect excellent sample recovery

High Preparative Throughput

The high surface area of the underlying silica particle, together with the larger number of available sites for interaction of the 1, 2 dihydroxypropane ligands, results in good preparative loading.
