HALO® C8

HALO® C8 Analytical HPLC Columns from AMT

HALO® C8 is a high-speed, high-performance liquid chromatography column based on a new Fused-Core® particle design. The Fused-Core® particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency. The densely bonded, extensively endcapped dimethyloctyl stationary phase of HALO® C8 provides a stable, reversed-phase packing that can be used for basic, acidic, or neutral compounds.

Available in 3 particle sizes:

  • HALO® 2 µm columns can meet or exceed the performance of most non-core sub-2 µm columns at pressures one-third to one-half the back pressure under the same conditions
  • HALO® 2.7 µm columns can meet or exceed the performance of most non-core sub-2 µm columns at pressures one-third to one-half the back pressure under the same conditions
  • HALO® 5 µm columns match the performance of totally porous 3 µm columns at roughly half the back pressure under the same conditions
