YMC-Pack CN
YMC-Pack CN 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.
In reversed phase mode, cyano (nitrile) phases are the most polar and least retentive of all reversed phase supports. Extremely hydrophobic compounds, which do not elute on standard C18 and C8 columns with typical reversed phase eluents, can be separated using cyano phases. Separations using reversed and normal phase and HILIC mechanisms can be carried out using this material.
