ACE Excel 1.7 C18-Amide 30x2.1mm

The Avantor ACE Excel C18-Amide HPLC/UHPLC column 30x2.1mm, 1.7µm, is based on an octadecylsilyl modification (other designations: ODS, RP-18, C18) with an embedded amide group for reversed-phase chromatography. The Avantor ACE Excel C18-Amide combines hydrophobic C18 retention with additional polar interactions and is therefore particularly interesting for polar substituted aromatics and compounds with hydrogen-bonding potential. The phase can also be used under strongly aqueous conditions and extends selectivity compared with classical alkyl phases. The Excel format supports high efficiency and fast analyses on UHPLC and HPLC systems. Typical applications are phenols, antioxidants, pesticides, caffeine, sweeteners, preservatives, vitamins as well as food and environmental analysis.

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.
