Raptor Biphenyl 1.8um 30 x 2.1mm

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. 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.

• Ideal for bioanalytical testing applications like drug and metabolite analyses.
• Heightened selectivity and retention for compounds that are hard to resolve or elute early on C18 and other phenyl chemistries.
• Limits ionization suppression and allows simple, MS-friendly mobile phases.
• Part of Restek’s Raptor LC column line featuring 1.8, 2.7, and 5 µm SPP core-shell silica.
