Restek Biphenyl: Leading Resolution in LC Since 2005
- Share:

- Separates a wider range of compounds than other phenyl and C18 chemistries.
- Increases sensitivity and selectivity in LC-MS while using simple, MS-friendly mobile phases.
- Restek’s most popular LC phase—available on traditional FPP and SPP core-shell silica.
Launched in 2005, the innovative Biphenyl (USP L11) is Restek’s most popular LC stationary phase because it is particularly adept at separating compounds that are hard to resolve or that elute early on C18 and other phenyl chemistries. As a result, rugged Biphenyl columns are extremely useful for fast separations—even with isobars—in drug, metabolite, and other analyses, especially those that require a mass spectrometer (MS). Increasing retention of early-eluting compounds can limit ionization suppression, and the Restek Biphenyl's heightened selectivity helps eliminate the need for complex mobile phases that are not well-suited for MS detection.
With ten years of unrivaled performance, Restek's time-tested Biphenyl has been proven to be the ideal column for clinical diagnostic, pain, pharmaceutical, and environmental labs seeking universal utility for mass spec applications. Restek was the first to bring you the benefits of the Biphenyl ligand, and our LC group has the veteran technical expertise to supply and support your lab better than anyone else.
Deconstructing the BiphenylWith USLC technology, Restek's LC experts have defined our columns' selectivity based on molecular interactions. The more rings shown, the more significant a role played in solute retention. Properties:
