HALO® C18 columns made with innovative Fused-Core® particle technology for excellent reproducibility and column lifetimes provide fast, high-resolution separations. Available in three particle sizes and a wide range of column dimensions, HALO® 90 Å C18 columns are optimized for high performance in HPLC, UHPLC and LCMS small molecule applications.

• Universal phase for acids, bases and neutral solutes with a wide range of hydrophobicities
• Excellent stability at low to mid mobile phase pH
• Widely published and most utilized stationary phase
• Particle sizes: 2, 2.7 or 5 μm superficially porous particle silica ('solid-core', 'core-shell')

HALO® guard columns are available for this phase.
