YMC-Pack C4
YMC-Pack C4 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.
YMC-Pack C4 is a low hydrophobicity material with a high coverage of monomeric bonded chemistry. Due to shorter alkyl chains it has a lower hydrophobicity than both C18 and C8 phases. Therefore retention times of non-polar samples tend to be shorter on YMC-Pack C4, making it an ideal choice for faster separations.
