YMC-Pack C8 (Octyl) Capillary Guard Columns

Monomerically Bonded, Fully Endcapped C8

C8 is the most commonly used column type following C18.  YMC-Pack C8 columns are prepared using exhaustive bonding of a monomeric octylsilane to totally porous and spherical silica gels.  The functionalized silica is then treated with an endcapping process which produces a moderate 10% carbon loading on the standard 120Å pore material.

Broad Application Range

C8 columns are well-suited for the separation of many compounds which are too strongly retained on C18 phases or require greater retention than C4.  It is the most versatile reversed-phase column and should be considered a first choice when outfitting a new laboratory.


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.
