YMC-Pack C4 (Butyl) Semi-Prep Guard Columns

Separate Mixed-Polarity Samples Quickly

YMC-Pack C4 (Butyl) columns are less hydrophobic than C8 or C18 packings, and generally utilize more aqueous eluents than either of these reversed-phase column types.  When compared to C8 and C18 columns (using the same eluents), C4 stationary phases show significantly shorter retention for non-polar compounds.  Retention of polar compounds, however, is not significantly affected.  Therefore, mixtures with a wide range of component polarity are best analyzed by YMC-Pack C4.  This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries.

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.
