Diol columns for Normal Phase in HPLC and UHPLC

Diol packing material can be universally used in different polar modes (NP, RP and HILIC). Diol bonded phases are a versatile alternative to unbonded silica for normal-phase separations with shorter equilibration times.

The hydroxyl groups provide good selectivity without excessive retention, caused by the weaker H-bonding of the diol layer than of silanols. Some diol bonded phases have been developed specifically for applications in the HILIC mode.
