Useful in Both Normal-Phase and Reversed-Phase Modes
YMC-Pack CN can be used for both normal-phase and reversed-phase analyses due to the medium polarity of the cyanopropyl phase bonded to the silica base particle. It can be used in normal-phase with low-polarity mobile phases such as hexane, or in reversed-phase with highly-polar mobile phases such as methanol and water. YMC-Pack CN can be useful for shortening analysis time in situations where retention is substantial using C18 or C8, or when separation optimization is difficult.
Alternative to Silica
In normal-phase mode, Cyano is a bonded phase that can be used as an alternative to silica. Bonded normal-phase columns have the advantage of faster equilibration and more uniform surface activity compared to bare silica gel. To extend column lifetime, continued switching back and forth between normal- and reversed-phase solvents should be avoided.
