The device comprises: a container that contains the air sample and has an opening; a sealing mechanism that opens or seals the opening; a sensor provided in the container and operative to sense a total concentration of particulates in the air sample within the container; and a controller connected to the sensor and operative to control the sealing mechanism. The controller is configured to: control the sealing mechanism to open the opening and the sensor to sense a first total concentration of particulates; control the sealing mechanism to seal the opening, so as to seal the container for a predetermined time period, and then control the sensor to sense a second total concentration of particulates; calculate a ratio of a concentration of tiny particulates to a total concentration of particulates based on a predetermined relationship between the ratio of the concentration of tiny particulates to the total concentration of particulates and a ratio of the second total concentration of particulates to the first total concentration of particulates; and calculate the concentration of tiny particulates in the air sample based on the first total concentration of particulates and the ratio of the concentration of tiny particulates to the total concentration of particulates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for detecting concentration of tiny particulates in air sample","description":"A device for detecting a concentration of tiny particulates in an air sample is provided.
