  • Gas chromatography using a thermal gradient that is substantially monotonically non-increasing and has a positive second derivative
    Patent number: 9678046
    Abstract: A system and method for thermal gradient gas chromatography wherein a front or injection end of a column is heated to a higher temperature than a back or detector end to thereby create a thermal gradient having a profile that is substantially monotonically non-increasing and has a positive second derivative, and then providing a heat source to raise the thermal gradient and cause it to remain stationary or to travel through the column while maintaining a desired profile.
    Type: Grant
    Filed: September 16, 2014
    Date of Patent: June 13, 2017
    Assignee: BRIGHAM YOUNG UNIVERSITY
    Inventors: H. Dennis Tolley, Anzi Wang, Samuel E. Tolley, Milton L. Lee, Aaron R. Hawkins
