  • Flow-field-induced temperature gradient gas chromatography
    Patent number: 10641748
    Abstract: The invention relates to a method, to a device, and to the use of a method for the gas-chromatic separation and determination of volatile substances in a carrier gas by means of a chromatographic separating capillary (1), wherein the separating capillary and/or an enveloping capillary (2) surrounding the separating capillary (1) is electrically conductive and is heated with current in the form of a resistance heater and is cooled by a forced convective flow by means of a fluid in the form of a gradient flow field in such a way that a continuous temperature gradient arises over the length of the separating capillary.
    Type: Grant
    Filed: July 12, 2019
    Date of Patent: May 5, 2020
    Inventor: Peter Boeker
