The ACQUITY BEH C8 sorbent is less retentive compared to the ACQUITY BEH C18 sorbent. A method developer may prefer the speed offered by a less retentive column, while improving peak shape and chromatographic performance. The trifunctionally bonded BEH particles offer the widest usable pH range (1-12), superior low pH stability, and ultra-low column bleed. 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.
