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

HALO® C8 HPLC columns from Advanced Materials Technology are based on Fused-Core® technology for high efficiency separations with low backpressures. The C8 phase is suited for a broad range of reversed phase applications and provides less hydrophobic retention compared to C18 phases. Available with 2 µm, 2.7 µm, and 5 µm for use with UHPLC or conventional HPLC equipment.
