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.
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.
