More Information
Summary:The present invention relates to a low-concentration air pollutant selective detection device and, more specifically, to a low-concentration air pollutant selective detection device capable of detecting a low-concentration air pollutant with high sensitivity, and selectively detecting an air pollutant when necessary. The low-concentration air pollutant selective detection device of the present invention comprises: a sensor which is located in a flow path, through which the gas moves, to detect contaminants in the gas; and a concentrator part which, by including an adsorbent that is positioned in the flow path of the gas that moves to the sensor and adsorbs contaminants in the gas, and a desorption means that is positioned adjacent to the adsorbent to individually desorb different contaminants from the adsorbent, delivers the concentrated contaminants to the sensor.
