YMC-Pack Ph (Phenyl) Semi-Prep Guard Columns

Unique Selectivity

Phenyl columns provide unique selectivity when compared to aliphatic straight chain reversed-phase materials such as C18, C8, and C4.  The π electrons of the phenyl group can interact with the aromatic ring(s) of an analyte to increase retention relative to non-aromatic species.  Phenyl also has application as an alternative to C18 and C4 for the analysis of peptides and proteins on both small-pore (120Å) and wide-pore (300Å) silica supports.  Retention is decreased on wide-pore phenyl phases relative to 120Å material.  Generally, as pore size increases, surface area decreases, resulting in shorter retention times.

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.
