Ultimasyil Phenyl 150Å HPLC Columns are engineered for advanced aromatic selectivity and improved retention of moderately large or bulky molecules. With a phenyl-bonded phase and a larger pore size of 150Å, these columns are ideal for analytes requiring enhanced π–π interaction and access to wider pore networks.
The columns are bonded on high-purity silica with a 12% carbon load and offer stable performance across a broad pH range. The reduced surface area (170 m²/g) facilitates faster mass transfer and sharper peaks in complex separations.
Key Features:
Pore Size: 150 Å – suited for larger or sterically hindered molecules
Carbon Load: 12% – balanced hydrophobicity for efficient retention
Surface Area: 170 m²/g – improves efficiency and peak shape
pH Range: 2 – 8 – compatible with most reversed-phase buffers
Molecular Weight Limit: <20,000 Da – ideal for medium-size peptides, proteins, and complex organics
