Ultrasep ES 100 Phenyl-Hexyl is a silica-based HPLC column with a 100 Å pore size and a phenyl-hexyl bonded phase. This stationary phase combines π–π interactions from the phenyl ring with hydrophobic retention from the hexyl chain, providing unique mixed-mode selectivity.
The dual interaction mechanism allows enhanced resolution of aromatic analytes, hydrophobic compounds, and mixtures of structurally similar substances. Compared to conventional C18 or pure phenyl phases, it offers orthogonal selectivity and improved versatility in method development.
Ultrasep ES 100 Phenyl-Hexyl combines aromatic selectivity with hydrophobic strength – the versatile choice for challenging reversed-phase HPLC separations.
