Abstract
A chemical substance concentrator is configured to concentrate a chemical substance contained in a gaseous sample. The concentrator includes a flow passage having a hollow part allowing the gaseous sample flows through the hollow part, first and second electrodes disposed on an inner wall of the flow passage, an electrode wiring connected to the first and second electrodes, a material layer disposed on the electrode wiring, and an adsorbent disposed on the material layer. The adsorbent is configured to adsorb the chemical substance and to desorb the adsorbed chemical substance. The chemical substance concentrator is capable of efficiently desorbing the adsorbed chemical substances.
