Encompass_Preferred

Torus DIOL Columns offer additional selectivity and robust chromatography. High-density diol surface bonding, similar to unbonded silica, enhances method robustness with additives.

  • Excellent peak shapes, broad, unique selectivities.
  • High efficiency and QC-ready robustness (OBD Technology).
  • Designed for achiral SFC separations; supports method transfer and scale-up.
  • Available in 1.7 and 5 μm chemistries in analytical and preparative formats.
  • Patent-pending two-stage functionalization (ethylene bridged hybrid BEH particles).
  • Hydrophilic surface bonding controls retention, minimizes unwanted interactions.
  • Second functionalization step provides individual selectivity and peak shape.
  • Maintains robust chromatographic performance throughout its lifetime.
  • Enables improved normal-phase chromatography for achiral and chiral separations.
