Description

technical field

[0001] The invention relates to the technical field of analytical instruments, in particular to a heating device and a thermal conductivity detector. Background technique

[0002] In the existing thermal conductivity detector, the heating process of the thermal conductivity cell is realized by heating the heating film arranged in the cavity of the thermal conductivity detector. Usually, only this heating method is used in the thermal conductivity detector. Single, and there is still room for improvement in the heating rate of the heat conduction pool. Contents of the invention

[0003] In view of this, the object of the present invention is to provide a heating device and a thermal conductivity detector. By adding an additional heating device to the thermal conduction pool of the thermal conductivity detector, the thermal conductivity pool is heated separately, and the heating film cooperates to realize The heating process of the heat conduction pool impro...
