Waters ACQUITY UPLC HSS C18 VanGuard Pre-column, 100Å, 1.8 µm, 2.1 mm X 5 mm, 3/pkg - 186003981

Price: £514.44


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.

ACQUITY UPLC HSS C18 chemistry is an ultra-performance general purpose C18 bonded phase that provides superior peak shape for bases, increased retention (vs. ACQUITY UPLC BEH C18 columns), and extremely long column lifetimes at low pH. ACQUITY HSS C18 columns are fully scalable and transferable to HPLC separations. 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.
