Raptor™ Biphenyl LC Columns, Restek
Chromatography Columns
The innovative Biphenyl 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.

  • Increased retention for dipolar, unsaturated, or conjugated solutes
  • Enhanced selectivity when used with methanolic mobile phase
  • Ideal for increasing sensitivity and selectivity in LC-MS analyses

As a result, the rugged Raptor™ Biphenyl column is extremely useful for fast separations in bioanalytical testing applications like drug and metabolite analyses, especially those that require a mass spectrometer (MS). Increasing retention of early-eluting compounds can limit ionization suppression, and the heightened selectivity helps eliminate the need for complex mobile phases that are not well-suited for MS detection.
