HALO 5

HALO-5 HPLC phases are based on the same Fused-Core technology as the original 2.7um UHPLC phases. They consist of solid core particles having a 0.6um porous silica layer fused to the surface. HALO-5 columns show extremely high plate numbers compared with conventional fully porous 5um phases and the equivalent or higher plate numbers compared with conventional 3um phases, but with approximately half the back pressure. This lower back pressure is well suited to legacy HPLC instruments.


HALO-5 columns are designed to boost the speed and resolution capability of HPLC to near UHPLC levels.

  • 5um Fused-Core particles
  • Scalable from UHPLC separations developed on 2.7um HALO columns
  • Low back pressure suited to legacy HPLC instruments
  • Stable to 9000 psi (600 bar)

All the phases produced in the original HALO series (2.7um phases) are also available in the HALO-5 series.

These chromatograms demonstrate the faster separation achieved using a HALO-5 superficially porous C18 column compared to a 5um totally porous column.
