ACQUITY UPLC BEH HILIC VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk

ACQUITY 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 the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
