YMC-Pack ODS-AL Analytical Guard Columns
Non-endcapped ODS
YMC-Pack ODS-AL uses not only hydrophobic interaction, but also secondary interactions caused by silanol groups that affect separation. This results in a different selectivity from conventional ODS columns. When ionic interaction is utilized, it is preferable to use a buffer in the mobile phase to achieve the best reproducibility.
YMC’s Guard Column Cartridge Systems for HPLC accept cartridges of 1.0, 2.1, 3.0, or 4.0mm inner diameters – in either 10mm or 20mm 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. Assembly is tool-free, simplifying cartridge replacement.
YMC Guard Column Cartridges require the use of a holder, P/N: XPGCH-Q1 for 10mm length and P/N: XPGCH-Q2 for 20mm length.

YMC’s Guard Columns for HPLC are available in 4.0mm and 5.0mm diameters and come in 10mm lengths. These guard columns are available with a comprehensive stationary phase selection offered by YMC, ensuring compatibility between the guard column and the analytical column. Unlike our guard cartridge columns, these guard columns do not require a holder, but do require a small jumper made from either stainless steel or PEEK tubing in order to connect them to the inlet of the analytical column.
