Waters ACQUITY UPLC Protein BEH C4 VanGuard Pre-column, 300 Å, 1.7 µm, 2.1 mm X 5 mm, 10K - 500K, 3/PK

Waters Protein Separation Technology (PrST) 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 VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
