Waters XBridge BEH HILIC VanGuard Pre-column, 130Å, 2.5 µm, 2.1 mm X 5 mm, 3/pkg - 186006295

XBridge BEH HILIC columns contain unbonded BEH substrate and are designed to retain and separate very polar compounds. These unique columns are optimized and tested to produce efficient, reproducible separations under HPLC HILIC conditions. More rugged than silica based HILIC phases, the BEH particle’s chemical stability results in long column lifetimes. The VanGuard pre-column connects directly to the inlet of an eXtended Performance column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
