Title: CHEMICAL SUBSTANCE CONCENTRATOR AND CHEMICAL SUBSTANCE DETECTION DEVICE
Abstract:
This chemical substance concentrator concentrates a chemical substance that is contained in a gaseous sample. This chemical substance concentrator is provided with: a flow channel that constitutes a hollow portion in which the gaseous sample flows; first and second electrodes which are provided on the inner wall of the flow channel; an electrode wiring line which is connected to the first and second electrodes; a material layer which is provided on the electrode wiring line; and an adsorbent which adsorbs and desorbs the chemical substance, while being provided on the material layer. This chemical substance concentrator is capable of efficiently desorbing a chemical substance which has been adsorbed.
