摘要
The disclosure is directed at apparatus for portable PM2.5 monitoring including a PM2.5 sampling device including a housing portion for collecting and separating air- borne particulate matter, an inlet port, connected to the housing portion, for receiving the air-borne particulate matter, a core portion, located within the housing portion, the core portion assisting in generating a cyclonic airflow pattern to produce a uniflow system for separating particulate matter below a predetermined size from particulate matter above a predetermined size within the air-borne particulate matter, and an outlet port for receiving the particulate matter below the predetermined size; a particle counter, connected to the outlet port, for receiving the particulate matter smaller than the predetermined size and for determining a mass of the particulate matter below the predetermined size; and a processor for determining a PM2.5 level based on the mass of the particulate matter below the predetermined size.
