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.
