Waters XBridge Protein BEH C4 Sentry Guard Cartridge, 300 Å, 3.5 µm, 2.1 mm x 10 mm, 2/PK

XBridge Protein BEH C4 Columns are QC tested and optimized to separate proteins based on size, hydrophobicity and isoelectric point. If you compare to traditional C18 phases, the C4 ligand is less retentive and will minimize protein carryover, increase protein recovery, and improve peak capacity. The Sentry Guard cartridge is designed to help extend column life of the analytical column.
