Agilent Polaris C18-A HPLC Columns
Agilent TechnologiesPolar-modified column; available in 3.0, 4.0, 4.6, 10, 21.2 and 50 mm id; 30 - 250 mm length. From the collapse-resistant pore structure of the base silica, to the "wettability" engineered into the bonded phases, Polaris columns have been designed for high aqueous conditions. The combination of high-phase density bonding, ultra pure silica and silanol shielding leads to excellent peak shape among polar-modified columns.
