Since 2005, the Restek Biphenyl has offered a greater degree of dispersion than conventional
phenyls and a greater degree of polarizability than phenyl hexyls, creating higher selectivity and
a greater range of usability. Because of these heightened interactions, this column shows substantial
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.
