Use two identical aerosol samplers in series and set the same sampling parameters to sample the aerosol air environment with uniform particle sizes; after sampling for a certain period of time, measure the air collected in the two samplers respectively. The amount of sol sample; repeat three times and take the arithmetic average; finally calculate the sampling efficiency of the sampler for aerosol of this particle size according to the formula. The method standard is based on the following conditions: two identical samplers have the same sampling efficiency for aerosols of a certain particle size; the samplers connected in series sample the aerosol with exactly the same gas volume.
