ACE 2 Phenyl Microbore HPLC Column 150x0.5mm (1/32" Connection)

The Avantor ACE Phenyl HPLC column 150x0.5mm, 2µm, features a phenyl group with a short propyl spacer for reversed-phase chromatography. The Avantor ACE Phenyl combines moderate hydrophobicity with aromatic selectivity and π–π interactions. This allows substituted aromatics, stereoisomers and analytes with phenyl or polarisable structures to be separated differently than on classical alkyl phases. Typical applications are parabens, flavonoids, steroids, taxanes, aromatic active substances, pharmaceutical impurities and food analysis.

Performance Characteristics and Benefits

• Ultra-inert, high-purity, base-deactivated silica particles
• Broad range of selectivity for reverse-phase, normal-phase, and HILIC applications
• Fully porous 100 Å and 300 Å phases for small molecules and biomolecules
• Excellent peak shapes for acidic, basic, and neutral analytes
• High reproducibility from column to column and batch to batch

Additional Information

The Avantor ACE Series is based on high-purity, spherical silica with very low metal contamination and targeted base deactivation. Controlled surface chemistry reduces the activity of free silanol groups, which promotes symmetrical peaks and reproducible retention times, particularly for basic analytes. The portfolio includes classic fully porous 100 Å phases, alternative selectivities, and 300 Å wide-pore materials for larger molecules. Using compatible Avantor ACE guard cartridges protects the silica backbone of the analytical column from matrix components and can extend the column’s service life.
