Ultra Biphenyl Columns (USP L11), Particle Size 3 μm, Length 150 mm, ID 4.6 mm, Restek (CAT#: STEM-C-0854-LC)

The Ultra Biphenyl Columns (USP L11) manufactured by Restek are made of high-purity, type-B silica that minimizes activity and creates high-density bonding. These columns are ideal for selective and reliable HPLC applications.
Ultra Biphenyl Columns (USP L11) feature a greater degree of dispersion than conventional phenyls and a greater degree of polarizability than phenyl hexyls to provide higher selectivity and a greater range of usability. Due to these heightened interactions, this column shows significant increases in retention-especially for dipolar, unsaturated, or conjugated solutes-and enhanced orthogonal selectivity when using methanol mobile phases. It is ideal for increasing sensitivity and selectivity in LC-MS analyses.
