Ultra Aromax is a unique reversed-phase material that exhibits extreme retention and selectivity for aromatic and/or unsaturated compounds.

• Particle size: 3 µm or 5 µm, spherical
• Pore size: 100 Å
• Carbon load: 17%
• End-cap: yes
• pH range and temperature limit: 2.5 to 8 and 80 °C
• USP phase code: L11
• Phase category and ligand type: phenyl and proprietary phenyl ligand

This column is a great alternative to Restek's Biphenyl phase when increased retention is required, and it’s an excellent choice for gradient LC-MS analyses when conventional columns are not giving adequate retention or selectivity.
