ACE 5 HILIC-B Analytical Guard Cartridge (x5)

The Avantor ACE HILIC-B guard cartridges 3.0-4.6mm, 5µm, are used for column protection of Avantor ACE HILIC-B HPLC and UHPLC columns with an internal diameter of 3.0-4.6mm are used. They protect the analytical HILIC column from sample matrix and particulate contaminants. For a reproducible HILIC method the guard cartridge should be used with the same HILIC phase as the main column; the suitable holder H0001 serves as the guard cartridge holder.

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.
