Ultra Aromax HPLC Column, 3um, 100 x 4.6mm

Ultra HPLC Columns The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications. Ultra Aromax is a unique reversed-phase material that exhibits extreme retention and selectivity for aromatic and/or unsaturated compounds. This column is a great alternative to our 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. Particle Size: 3 µm or 5 µm, spherical Pore Size: 100 Å Carbon Load: 17% End-Cap: yes pH Range: 2.5 to 8 Temperature Limit: 80°C USP Phase Code: L11 Phase Category: phenyl Ligand Type: proprietary phenyl ligand
