YMC-Pack Silica
YMC-Pack Silica 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.
Due to the highly sophisticated production process YMC’s highly spherical silica material shows premium performance and great lot-to-lot reproducibility. The reason for this can be summarised in two main qualities: the very narrow physical and chemical product specifications and the outstanding purity.
