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.
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.
Columns, Guards and Accessories are only available for purchase online in North America or through our distributors.
To purchase consumables outside North America, please find your local distributor.
