PM10 采样器的开发是多个国际原子能机构赞助的涉及环境空气颗粒采样和分析的协调研究计划的一个组成部分。为每个参与者提供了这样一个采样器，以便每个参与组都可以获得可比较的样品。因此，为了了解该采样器的特性，我们进行了多项特性研究，其中我们检查了冲击器入口的空气动力学收集特性和样品质量收集的再现性，将比利时加工的采样器与美国相同设计制造的采样器进行了比较，并获得了可比较的结果。采样器与商用 PM10 并排运行beta 规和 IMPROVE 设计 2.5 μm 切点旋风分离器，尽管采样器未按照参考采样器认证要求进行风洞测试，但它确实提供了通常遵循 PM10 采样器指南的收集效率。 (C) 1997 年美国气溶胶研究协会。
An integral part of several International Atomic Energy Agency sponsored coordinated research programmes involving the sampling and analysis of ambient airborne particules was the development of a PM10 sampler. Each participant was provided with such a sampler so that comparable samples would be obtained by each of the participating groups, Thus, in order to understand the characteristics of this sampler, we undertoke several characterization studies in which we examined the aerodynamic collection characteristics of the impactor inlet and the reproducibility of the sample mass collection, One of the samplers machined in Belgium was compared with one built from the same design in the U.S. and comparable results were obtained, The sampler was operated side-by-side with a commercial PM10 beta gauge and an IMPROVE-design 2.5 mu m cut-point cyclone, Although the sampler was not wind tunnel tested as required for certification as a reference sampler, it does provide a collection efficiency that generally follows the guidelines for a PM10 sampler.
