YMC-Pack C8 (Octyl) Semi-Prep 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.

Guard Cartridges

Semi-Prep Guard Cartridges: Features & Benefits

YMC’s Guard Column Cartridge Systems for Semi-Prep HPLC utilize cartridges of 10, 20, or 30mm inner diameters – in 10mm lengths. Cartridges are available with a comprehensive selection including all stationary phase chemistries offered by YMC, ensuring compatibility between the guard column and the analytical column (including columns by other manufacturers). Assembly is tool-free, simplifying cartridge replacement.
YMC Guard Column Cartridges require the use of a holder, P/N: XPCHSPW1 for 10mm I.D., P/N: XPCHSPW2 for 20mm I.D. and P/N: XPCHSPW3 for 30mm I.D.
