Abstract
A uniform aerosol deposit sampling device includes a first housing and a second housing. The first housing has an air inlet and a first chamber. The second housing has an air outlet, an second chamber, a filter holder and a flow guiding portion. The filter holder is provided for securing an air-penetratable supporting pad and a filter media. The flow guiding portion is a substantially conical and gradually narrowing. The flow guiding portion has a semi-conical angle ranged from 15 to 85 degrees. So, the flow guiding portion makes the entire air flow smooth and evenly distributed. The aerosols will be evenly distributed and uniformly deposited on the filter media. And, it is easy to evaluate the amount and composition of the aerosols.
