  • PH stable chromatographic media using templated multilayer organic/inorganic grafting
    Patent number: 8658038
    Abstract: An advanced silica gel sorbent for use in chromatographic separations that has been chemically modified by surface polycondensation of a trifunctional and/or difunctional organosilane. The chromatographic media exhibits a wider pH range and improved pH stability as compared to other silica gel based sorbents, while retaining all other positive aspects attributed to silica gel based sorbents. A method of forming the advanced silica gel sorbent by Templated Multilayer Inorganic/Organic Grafting.
    Type: Grant
    Filed: June 30, 2009
    Date of Patent: February 25, 2014
    Assignee: Phenomenex, Inc.
    Inventors: Ismail M. Rustamov, Michael C. Chitty, Tivadar Farkas, Lawrence Loo, Emmet Welch
