ACE Excel 1.7 NH2 30x3.0mm

The Avantor ACE Excel NH2 HPLC/UHPLC column 30x3.0mm, 1.7µm, has an aminopropyl modification and can be used in normal phase, HILIC and strongly aqueous reversed phase. The Avantor ACE Excel NH2 provides polar, basic and ionic interactions and is therefore of interest for very hydrophilic compounds. The phase is frequently used when neutral or weakly charged carbohydrates and related polar analytes show insufficient retention on conventional reversed phases. The Excel format supports high efficiency and fast analyses on UHPLC and HPLC systems. Typical applications are sugars, mono- and disaccharides, acarbose, lactulose solutions, vitamin E analysis and alcohol-related biomarkers.

Features and Benefits

• UHPLC/HPLC hardware for high pressure stability and low system dispersion
• Ultra-inert, base-deactivated, fully porous silica particles
• Wide range of phases for rapid method development
• Excellent peak shape and reproducibility for acidic, basic, and neutral analytes
• Particle sizes for high resolution and fast routine analyses

Additional Information

Avantor ACE Excel combines ACE silica chemistry with a UHPLC-compatible column format. The high-purity, base-deactivated silica matrix minimizes secondary interactions and ensures reproducible retention times. The combination of inert silica, controlled ligand bonding, and pressure-stable hardware allows methods to be implemented in both UHPLC and conventional HPLC systems. Compatible Avantor ACE Excel guard cartridges protect the analytical column from the sample matrix and help maintain the performance of the Excel method over extended runs.
