  • Publication number: 20190134604
    Abstract: The present invention provides novel chromatographic materials. e.g., for chromatographic separations, processes for their preparation and separations devices containing the chromatographic materials. The chromatographic materials of the invention have controlled porosity and comprise a chromatographic core material and one or more layers of chromatographic surface material which each independently provide an average pore diameter, an average pore volume, or a specific surface area such that the combined layers form a chromatographic material having a predetermined or desired pattern of porosity from the core material to the outermost surface. The materials are useful for HPLC separations, normal-phase selarations, reversed-phase separations, chiral separations, HILIC separations, SFC separations, affinity separations, perfusive separations, partially perfusive separations, and SEC separations.

  • Patent number: 9933399
    Abstract: The present technology uses one or more separating segments, i.e. chromatography columns, aligned in series along a flow path. The separating segments are divided by a plurality of heating elements or are heated directly. The heating elements heat the supercritical mobile phase and sample to replace heat lost due to axial expansion of the mobile phase along the mobile phase flow path.
