HALO® BIOCLASS Diphenyl 400 Å protein columns made with innovative large pore Fused-Core® particle technology provide narrower peaks and better recoveries for high-resolution separations of large biomolecules such as mAbs, versus smaller pore size columns. HALO® 400 Å columns are optimized for high performance in HPLC, UHPLC and LCMS large molecule applications, delivering excellent reproducibility and column lifetimes.

• Ideal for large protein analysis such as mAbs and polypeptides
• Well suited for high speed protein separations
• Exceptional recovery performance and temperature stability from 40 to 90 °C
• Outstanding low bleed performance

Alternate selectivities with HALO® Protein C4, Diphenyl and ES-C18 phases.

HALO® guard columns are available for this phase.
