Abstract

This invention provides a kind of aerosol homogeneous sampling filter paper cassette, which comprises a first cassette section having a gas inlet port and a first chamber connected to each other; a second cassette section having a second chamber connected to the first chamber, and a current-guiding gas-discharging section; and a filter paper fixation section located between the second chamber and the current-guiding gas-discharging section and used for fixing a permeable support pad and a filter paper. The current-guiding gas-discharging section is connected to a gas-discharging port whose cross-sectional surface area is smaller than that of the second chamber. The current-guiding gas-discharging section is approximately in a tapering conical structure and its average half cone angle is between 15 and 85 DEG. Therefore, this current-guiding gas-discharging section has the advantages of homogeneous air flow, allowing micro particles to be homogeneously distributed on the filter paper, easy calculation of micro particle content, composition and concentration, etc.
