SUPERFICIALLY POROUS MATERIALS COMPRISING A SUBSTANTIALLY NONPOROUS HYBRID CORE HAVING NARROW PARTICLE SIZE DISTRIBUTION; PROCESS FOR THE PREPARATION THEREOF; AND USE THEREOF FOR CHROMATOGRAPHIC SEPARATIONS

摘要

The present invention provides novel chromatographic materials, e.g., for chromatographic separations, processes for its preparation and separations devices containing the chromatographic material; separations devices, chromatographic columns and kits comprising the same; and methods for the preparation thereof. The chromatographic materials of the invention are chromatographic materials comprising having a narrow particle size distribution.
