Significant difference exists between the sampling efficiency of gravity. plate and those of Andersensampler and THK-201 sampler when they are used for sampling airborne bacterial particles.
The number density is obtained by transforming the aerosol quality density which is gained directly from Andersen stage sampler.
本文采用安德森分级采样直接获得的大气气溶胶质量密度换算成数密度。

The impact of sampling time on concentration of collected bacterium, fungus particles and mid-value diameter of particle number are studied by ANDERSEN bioparticle sampler in lab.
