Passive aerosol sampler and methods |
摘要 |
A miniature, passive aerosol particle sampler comprises a scanning electron microscopy mount provided with a collection surface and a removable mesh cover comprising a spacer ring and a mesh sheet. A sampling and analysis method comprises scanning electron microscopy and image analysis to determine a particle-count size distribution. A deposition velocity model comprising a theoretical component and an empirical component is used to determine from the particle-count size distribution the average airborne mass concentration of aerosol particles to which the sampler was exposed.
