  • Surfactant-based monolithic columns, methods for making the same, and methods for using the same
    Patent number: 10119003
    Abstract: A method for making a surfactant-based monolithic column is provided. The method comprises providing a mixture comprising at least one surfactant monomer, at least one crosslinker, at least one initiator, and at least one porogen and polymerizing the mixture to form the surfactant-based monolithic column. The present disclosure also provides a surfactant-based monolithic column, a method for separating molecules, and a process for preparing a surfactant monomer.
    Type: Grant

  • Polymeric sulfated surfactants for capillary electrophoresis (CE) and CE-mass spectrometry (CE-MS)
    Patent number: 8168440
    Abstract: The present invention relates generally to methods for enantiomeric separation of complex chemical mixtures using micelles of surfactant molecules that have a sulfate or sulfonate head group, a chiral selector, a linker, and a hydrophobic tail. Also provided are micelle compositions with sulfate or sulfonated head groups, methods of manufacture, and applications thereof. In particular, the micelles of the present invention provide an efficient enantiomeric separation and detection techniques for use in capillary electrophoresis and capillary electrophoresis with mass spectrometry.
