NEUROSYIL Phenyl-Hexyl HPLC Columns: 100 Å* are designed with a phenyl-hexyl bonded stationary phase that combines π–π interactions from the phenyl group and hydrophobic interactions from the hexyl chain. This dual interaction mechanism provides superior selectivity for aromatic compounds, polar analytes, and complex mixtures. With a 100 Å pore size, these columns offer sharp peak shapes, high resolution, and reproducible performance—ideal for pharmaceutical, biochemical, and environmental reversed-phase applications.
