U(H)PLC Guard Column ACQUITY CSH Phenyl, 130 Å, 1.7 µm, 2.1 x 5 mm, 3 pc/PAK

ACQUITY CSH Phenyl-Hexyl columns are used to provide alternative analyte selectivity and are a valuable tool for method development. The trifunctionally bonded C6 phenyl ligand is a robust, low bleed sorbents that selectively retains polyaromotic compounds through pi-pi interactions. 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.
