Acquity is a brand name for UPLC® columns from the US manufacturer Waters. The spherical, sub-2 μm silica particles are available with various modifications and particle technologies (BEH, CSH, HSS), providing high efficiencies along with a wide selectivity space. Rugged base-particle technologies provide very high column stability and ultimate flexibility for high-throughput method development.
