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.

Claim (Index 25):
The method as claimed in  claim 21 ,\n wherein the gradient of the flow speed is produced by continuously increasing the flow resistance along a helical groove in a hollow body containing a porous material, wherein the separation capillary and/or sheath capillary is/are inserted in a helical groove in a wall of the hollow body containing the porous material.
