Pinnacle® DB Biphenyl HPLC Columns (USP L11), Restek

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.

Greater dispersion
Increased retention
Ideal for increasing sensitivity

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.

Pinnacle DB columns are 100% manufactured by Restek in our Bellefonte, Pennsylvania facility. Because performance begins with the support, our Pinnacle DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, we bond them with a wide variety of phases to give chromatographers a stable and selective column. Get the most out of your UHPLC system. Combine selectivity and efficiency by using Restek Pinnacle DB UHPLC columns.

It is ideal for increasing sensitivity and selectivity in LC-MS analyses.
