Abstract: The present invention relates to a kit for concentrating low-concentration air pollutants, and to a concentration kit for concentrating low-concentration air pollutants, and then desorbing same so as to detect the components and concentrations of the pollutants. The present invention comprises: a sensor positioned on a channel in which gas moves, so as to detect pollutants in the gas; and a concentration part, which comprises an adsorbent for adsorbing and desorbing the pollutants in the gas moving to the sensor, so as to transfer concentrated pollutants to the sensor.
