ACE 1.7 HILIC-B 75x3.0mm

The Avantor ACE HILIC-B HPLC-/UHPLC column 75x3.0mm, 1.7µm, has a proprietary aminopropyl-like HILIC surface for hydrophilic interaction chromatography. The Avantor ACE HILIC-B displays basic character and can enable anion-exchange-like interactions with acidic or negatively charged analytes. This results in a distinctly different selectivity compared with HILIC-A or neutral HILIC phases. Typical applications are penicillins, sugars, fendizoic acid, related acidic compounds, carbohydrates and method development for very polar analytes.

Features and Benefits

• Three proprietary HILIC phases for systematic method development
• Retention of polar and highly polar analytes outside the scope of conventional reverse-phase separation
• Distinct acidic, basic, and neutral selectivity profiles
• Ultra-inert silica base for reproducible HILIC separations
• Suitable for LC-MS-friendly mobile phases with a high organic content

Additional Notes

Avantor ACE HILIC uses ultra-inert silica particles with various proprietary polar surface chemistries. The three HILIC phases—HILIC-A, HILIC-B, and HILIC-N—were developed for systematic selectivity screening, as they represent different ionic and neutral interactions. In contrast to reverse-phase chromatography, retention in HILIC is typically determined by a water-rich layer on the polar stationary phase and mobile phases with a high organic content. Appropriate guard cartridges protect the sensitive HILIC method from matrix components and help ensure stable retention times.
