Phenyl columns for Reversed Phase in HPLC and UHPLC
Phenyl stationary phases (USP L11) in reversed phase mode with alternative selectivity for
- aromatic and moderately pi-pi interaction polar analytes or
- mixtures with varying polarity and aromaticity.
The polarity is similar to C8 modification but with different selectivity for polar aromatics, polycyclic aromatic hydrocarbons, fatty acids etc.
Phenyl phases with a classical slightly hydrophobic endcapping or without endcapping.
