PROBLEM TO BE SOLVED: To provide an apparatus for continuously and automatically analyzing element types constituting suspended particulate matter in the atmosphere. A sample atmosphere taken in from a sample inlet by suction is classified into air containing all of CP and air containing only FP by a classifying unit, and air containing only FP is separated by a flow dividing device. Divided. The diverted air containing FP is collected by the collection position 5 a of the tape filter 5. The time period for collecting the sample is set to be the same as the conditioning conditions of the FEM method, for example, 24 hours, and the collected fine particles are in a dry state. Then, the mass measurement unit 15 performs mass analysis by the β-ray absorption method. [Selection] Figure 1 |
