HPLC columns, Raptor™ Biphenyl (USP L11)

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).

These columns have increased retention for dipolar, unsaturated, or conjugated solutes
They have enhanced selectivity when used with methanolic mobile phase
Increasing retention of early-eluting compounds can limit ionisation suppression
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 ionisation suppression, and the heightened selectivity helps eliminate the need for complex mobile phases that are not well-suited for MS detection.
