DESCRIPTION
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.
