Abstract
The present invention relates to superficially porous particles (SPPs), also called core-shell, porous shell or fused core particles, which are state-of-the-art support materials used in the production of HPLC columns. Hydrolytically stable, highly selective superficially porous particle (SPP) hydrophilic interaction liquid chromatographic (HILIC) stationary phases having higher efficiencies and shorter retention times than analogous stationary phases on fully porous particles (FPP) is provided.
