Scope
The main technical content is: using two identical aerosol samplers in series and setting the same sampling parameters to sample the aerosol air environment with uniform particle size; after sampling for a certain period of time, the amount of aerosol samples collected by the two samplers is measured respectively; the process is repeated three times, and the arithmetic average value is taken; finally, the sampling efficiency of the sampler for aerosols of a certain size is calculated according to the formula. The standard of this method is based on the following conditions: the sampling efficiency of two identical samplers for aerosols of a certain size is the same; the amount of aerosol gas sampled by the samplers in series is exactly the same
