YMC-Pack Pro C4
YMC-Pack Pro 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.
With Pro C4, YMC offers a stationary phase based on the well-known ultra pure silica of the ProFamily. Compared to a C18 phase with the same eluent, C4 phases are less hydrophobic and gives shorter retention times for non-polar compounds while the retention time of polar analytes are virtually unaffected. This makes the Pro C4 an interesting alternative especially when short analysis times are required.
