Techniques for measuring particle size distribution of particulate matter emitted from animal feeding operations

Determination of Aerosol Size Distribution from Angular Light-Scattering Signals by Using a SPSO-DE Hybrid Algorithm

“…During the past several years, various types of methods have been proposed to study the ASDs, e.g., the aerodynamic method, the optical measurement method, electrical mobility and condensation 2 of 14 method, electrical sensing zone method and the electron microscopy method [9]. Owing to offering a useful and effective approach, reliable measurement results and broad size ranges, the optical measurement method coupled with inverse methods has drawn much attention in the field of determining the ASDs [10].…”

Retrieval of aerosol size distribution using improved quantum-behaved particle swarm optimization on spectral extinction measurements

“…During the past two decades, various methods have been introduced to determine particle size distribution (PSD), including aerodynamic, optical, ultrasonic, electrical mobility, and condensation methods (Wang-Li et al, 2013). Since properties of aerosols can be derived by measuring a variety of light scattering properties, such as extinction or other scattering information, optical measurement methods have attracted much attention.…”

Airborne particles detection and sizing at single particle level by a novel electrical current pulse sensor

“…For light scattering method, however, the size measurement can be interfered by the color, refractive index and composition of the particle [18][19][20]. Furthermore, it cannot provide real-time size distribution measurement [21] and the commercial instruments are very expensive and large in size.…”
