XBridge Protein BEH C4 Guard Column, 300Å, 5 µm, 2.1 mm X 30 mm, 1/pk

Primarily used for legacy methods. If you are developing a new method, please consider our newer technology XBridge Protein BEH C4 VanGuard Cartridge p/n: 186009131.

Waters XBridge Protein BEH C4 Guard Column, 300Å, 5 µm, 2.1 mm X 30 mm Protein Separation Technology (PrST) columns are QC tested and optimized to separate proteins based on size, hydrophobicity and isoelectric point. If you compare traditional to C18 phases, the C4 ligand is less retentive and will minimize protein carryover, increase protein recovery and improve peak capacity.
