YMC-Pack CN (Cyano) Semi-Prep Guard Columns

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.
