ChromX® Phenyl by CHROMOSEP is a high-performance aliphatically modified reverse phase HPLC column engineered for exceptional selectivity and reproducibility. Featuring gas-phase endcapping and alkylphenyl modification, this column enables strong π–π interactions that enhance the separation of aromatic and conjugated compounds, including both polar and non-polar hydrocarbons and fatty acids. Its unique selectivity profile, distinct from traditional C18 columns, makes it especially effective for complex aromatic separations. With excellent column-to-column reproducibility and high mechanical stability, ChromX® Phenyl ensures consistent and reliable results for the analysis of halogenated aromatics, phenols, benzenes, amines, and regioisomers. Ideal for research and pharmaceutical applications, this column provides sharp peak resolution, superior efficiency, and dependable performance across challenging analytical workflows.
