CHROMATOGRAPHIC COLUMNS AND SEPARATION DEVICES COMPRISING A SUPERFICIALLY POROUS MATERIAL; AND USE THEREOF FOR SUPERCRITICAL FLUID CHROMATOGRAPHY AND OTHER CHROMATOGRAPHY

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 superficially porous chromatographic particulate materials comprising sized less than 2 microns.
