Waters ACQUITY UPLC PrST C4 VanGuard Pre-column, 300Å, 1.7 µm, 2.1 mm X 5 mm, 3/pkg - 186004623

Price: £537.77

VanGuard Pre-Columns are guard columns designed for use with the ACQUITY UPLC system and are the first guard columns specifically designed for routine use at pressures up to 15000 psi (1000 bar). VanGuard Pre-Columns use an ultra-low volume, patent-pending design that efficiently protects UPLC column performance in applications where samples are complex and unpredictable and the analytical workload is demanding and/or increasing. VanGuard Pre-Columns are packed with the same particles and bonded phases currently available in the ACQUITY UPLC column family.

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.
