  • Nanocomposites and their application as monolith columns
    Patent number: 9289747
    Abstract: Novel materials for chromatographic separations, processes for their preparation, and separation devices containing the chromatographic materials. In particular, hybrid inorganic/organic monolith materials comprising a polymerized scaffolding nanocomposite (PSN), wherein the nanocomposite contains a scaffolding functionally capable of chemically interacting with a surface of a second material are described. The hybrid inorganic/organic materials have enhanced wall adhesion and increased resistance to shrinkage as compared to prior art monolith materials. The improved adhesion of the monoliths enable the preparation of capillary columns with an internal diameter (I.D.)?50 ?m.
    Type: Grant
    Filed: May 12, 2014
    Date of Patent: March 22, 2016
    Assignee: Waters Technologies Corporation
