Reversed Phase Columns (C18 Column)

InertSustain AX-C18 Analytical Columns

InertSustain AX-C18 is a mix-mode column, where C18 groups and tertiary amino groups are chemically bonded to silica gel. It provides hydrophobic interaction and the electrostatic interaction by AX group works. By controlling the amount of AX group, acidic compounds can be eluted even in buffer concentration range used with LC/MS. It performs an excellent reproducibility and stable quality.
