  • Micromachined gas chromatography columns for fast separation of Organophosphonate and Organosulfur compounds and methods for deactivating same
    Patent number: 8152908
    Abstract: Improved microcolumns and methods for producing microcolumns particularly suitable for use in gas chromatographs are disclosed. In particular, following deposition of the stationary phase coating, the microcolumns are subjected to a postcoating treatment with a molecule that binds to the active sites in the stationary phase column thereby eliminating or reducing loss of gas chromatograph performance associated with those active sites. The postcoating treatment molecule binds to the same active sites as the analytes of interest.
    Type: Grant
    Filed: December 18, 2008
    Date of Patent: April 10, 2012
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Richard I. Masel, Adarsh D. Radadia
  • Column design for micro gas chromatograph
    Patent number: 8123841
    Abstract: Improved micro-columns and methods for producing micro-columns particularly suitable for use in gas chromatographs are disclosed. In particular, following deposition of the stationary phase coating, the micro-columns are subjected to a postcoating treatment with a molecule that binds to the active sites in the stationary phase micro-column thereby eliminating or reducing loss of gas chromatograph performance associated with those active sites. The postcoating treatment molecule binds to the same active sites as the analytes of interest.
