Halo-Cover2Fused-Core™ particle technology for hyper-fast and super-rugged HPLC columns.

  • 2.7 µm semi-porous particles manufactured with Fused-Core™ technology
  • The same high efficiency as with sub 2 µm particles but with considerable lower backpressure
  • Extremely fast separations – even with a traditional HPLC-system
  • Very robust columns
  • Can be used at extreme pressures
  • 2 µm frits in the column can be used because of tight particle size distribution
  • Developed by Dr. Jack Kirkland, one of the pioneers in chromatography

Biotech AB is responsible for the sales of the HALO™-columns in the Nordic market (Sweden, Norway, Denmark, Finland)

HALO-5-CoverHALO Fused-Core particles with a particle size of 5µm.

The HALO 5 µm particles are exciting and novel because they can be packed into columns that will change the way you will think about HPLC by providing the following benefits:

  • The highest plate counts versus any other 5-micron column you can buy (> 150,000 plates per meter)
  • Equivalent or higher number of plates as most 3-micron columns with one-half the pressure
  • The ruggedness of 5-micron columns (stable packed beds, resistance to pluggage) with the performance of 3-micron columns
  • Improved productivity resulting from having the same thin porous layer as 2.7-micron HALO columns allowing high efficiencies at faster flow rates
  • Low back-pressure well suited to legacy HPLC instruments
  • Scalable from UHPLC separations developed on 2.7-micron HALO columns
  • Available in lengths from 20-250mm and ID 2.1, 3.0 and 4.6mm

We offer 5 different phases in the 5 micron particle dimension These are:

  • C18
  • PFP
  • Phenyl-Hexyl
  • C8
  • ES-CN
These HALO-5 columns can be delivered in all of the usual column dimensions with an added plus – 250 mm long columns.
