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

ACQUITY UPLC HSS C18 SB columns are used for low pH separations that contain complex mixtures of basic and non-basic compounds. ACQUITY HSS C18 SB columns give you alternative analyte selectivity compared to most modern, high coverage, fully endcapped C18 stationary phases. ACQUITY HSS C18 SB 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.
