YMC-Pack CN (Cyano) Capillary 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.


Capillary Guard Columns: Features & Benefitsymca_3

Guard columns are recommended for challenging matrices or for use as trapping columns.  YMC capillary guard columns are connected directly to the analytical column using the supplied column coupler.

A column coupler is supplied with every pack of YMC capillary guard cartridges to guarantee an optimum connection with low dead volume.  A polymer-based (PCTFE) coupler is provided for 1/16” columns, while a stainless steel coupler is provided for 1/32” columns.  Additional couplers can be purchased separately if required.
