High Purity, High Sample Recovery
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery. The absence of silica impurities reduces non-specific sample adsorption, which lowers sample recovery and may cause unusual peak shapes.
High Sample Loading, High Mechanical Stability
The totally porous nature of the silica found in YMC-Pack SIL columns provides high sample loading. With some competitive silicas, the level of porosity would make the particles prone to fracture, resulting in fines and high backpressure. However, the high chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength.
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.

YMC’s semi-preparative & preparative Guard Columns for HPLC are available in 10mm diameter with 30mm length as well as 20mm, 30mm, and 50mm diameters with 50mm lengths. These guard columns are available with a comprehensive stationary phase selection offered by YMC, ensuring compatibility between the guard column and the semi-preparative or preparative column. Unlike our guard cartridge columns, these guard columns do not require a holder.
(No holder required)
