YMC-Pack Diol-NP Analytical Guard Cartridge, 120 Å, 5 um, 20 mm x 3.0 mm ID, 5/pk

YMC-Pack Diol-NP is a versatile alternative to silica for normal phase separations and provides much better reproducibility when compared to bare silica material. It shows typical normal phase retention behavior when used with low-polarity mobile phases due to hydroxyl groups on the surface of the stationary phase acting as polar groups.

Hydrogen bonding with the Diol-NP layer is not as strong as with silanols on a bare silica surface. As a result, the bonded layer’s hydroxyl groups provide good selectivity without excessive retention. YMC-Pack Diol-NP can also be used in HILIC-mode with organic/water mobile phases.
