摘要： A three-stage dust sampler makes use of a porous foam as the impactor substrates. The sampler includes an annular inlet which conforms to ISO/CEN/ACGIH inhalable sampling criteria, two impactor stages to classify thoracic and respirable particles and a final filter to collect respirable particles after the impactors. For 100 ppi polymer foam substrates, and a flow rate of 3.2 lpm, the collection efficiency curves of the thoracic and respirable dust matches ISO/CEN/ACGIH criteria when the jet-to-plate distance is 1.0. The cut-off aerodynamic diameter is 9.6 and 4.0 μm for the first and second impactor stages, respectively, and √{square root over (stk50)} is 0.39 for both stages. The collection efficiencies for solid particles is equal to that for liquid particles, indicating that there is no solid particle bouncing from the foam substrates.

摘要： 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.
摘要翻译：均匀的气溶胶沉积物取样装置包括第一壳体和第二壳体。第一壳体具有空气入口和第一室。第二壳体具有空气出口，第二室，过滤器保持件和流动引导部。过滤器保持器被设置用于固定可透气的支撑垫和过滤介质。流动引导部分基本上是圆锥形并逐渐变细。流动引导部分具有15至85度的半锥形角度。因此，导流部使整个气流均匀分布。气溶胶将均匀分布均匀地沉积在过滤介质上。而且，很容易评估气溶胶的数量和组成。
