YMC-Pack ODS-AL Capillary Guard Columns

Non-endcapped ODS

YMC-Pack ODS-AL uses not only hydrophobic interaction, but also secondary interactions caused by silanol groups that affect separation.  This results in a different selectivity from conventional ODS columns.  When ionic interaction is utilized, it is preferable to use a buffer in the mobile phase to achieve the best reproducibility.


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.
