A non-endcapped C18 stationary phase bonded to a 1.8 μm high strength silica (HSS) particle substrate was developed to provide different selectivities in UltraPerformance Liquid Chromatography (UPLC® technology) separations. ACQUITY UPLC® HSS C18 SB (Selectivity for Bases) columns provide alternate selectivity for bases under acidic conditions, and provide an additional UPLC method development tool.
