Characterization and analysis of airborne solid submicrometer particles have received considerable attention. Representative collection of particles to be analyzed is a fundamental requirement. Herein we review the efficiency of particle sampling using Nuclepore filters. The available theoretical models based on different collection mechanisms: diffusion, interception, and impaction, are explored and compared. Experimentally measured values are combined to analyze the effect of the particle capturing mechanism on collection efficiency based on different parameters like filter pore size and flow face velocity. In addition, a method for experimental collection efficiency analysis combined with theoretical modeling is developed by considering the model’s applicability. The diffusion model proposed by Marre fits the sampling conditions with a small most penetrating particle size (MPPS). The combined efficiency models have corrected the inappropriateness of considering particle deposition mechanisms separately. They are recommended if the assumptions are satisfied.

气载固体亚微米颗粒的表征和分析已受到相当多的关注。有代表性的要分析的粒子收集是基本要求。本文中，我们回顾了使用Nuclepore过滤器进行颗粒采样的效率。探索和比较了基于不同收集机制（扩散，拦截和撞击）的可用理论模型。根据不同的参数（如过滤器孔径和流面速度），结合实验测量值来分析颗粒捕获机制对收集效率的影响。此外，通过考虑模型的适用性，开发了一种结合理论模型进行实验收集效率分析的方法。Marre提出的扩散模型适合最小穿透颗粒尺寸（MPPS）的采样条件。结合的效率模型已经纠正了单独考虑颗粒沉积机理的不适当性。如果满足假设，则建议使用它们。
