YMCbasic Guard Columns

YMC recommends that you always use a guard column with the same packing material and of the recommended inner diameter for your column. A YMC guard column is normally composed of a cartridge holder and a guard cartridge. The holder can be used repeatedly. Guard cartridges should be changed frequently in order to maximise their protection of the main column.

    YMCbasic shows a different hydrophobicity and represents a complementing selectivity to C8 and C18 materials.

      YMCbasic offers high resolution and excellent peak symmetry for basic compounds without the need of ion pair reagents or amine modifiers. Unlike many base-deactivated phases, YMCbasic is also suitable for separation of acidic compounds, showing slight retention of highly polar acid compounds such as maleate.
