ACE Excel 5 CN-ES 150x4.6mm

The Avantor ACE Excel CN-ES HPLC/UHPLC column 150x4.6mm, 5µm, features a cyano group with an extended alkyl spacer and has been developed for normal-phase and reversed-phase chromatography. The special feature of the Avantor ACE Excel CN-ES lies in the combination of cyano selectivity, increased stability and stronger retention than many classical CN phases. In addition to dipole–dipole interactions, moderate hydrophobic contributions can also be exploited, resulting in alternative separation patterns. The Excel format supports high efficiency and fast analyses on UHPLC and HPLC systems. Typical applications include steroids, vitamin K, aspirin-related substances, polar analytes, explosive residues and methods intended to be transferred between normal phase and reversed phase.

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.
