YMC-Pack Diol

YMC-Pack Diol-NP Semi-Prep 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.

      YMC-Pack Diol NP is available in 10, 20 and 30 mm ID for semi-prep applications. With YMC-Actus, a specific hardware and packing technology has been applied to provide a uniform packing density, which results in longer lifetime than conventional semi-preparative columns. YMC-Actus columns offer outstanding efficiency without compromising resolution.
