Measurement method of NO, NO2, SO2, O3 and NH3 concentrations in the atmosphere using a diffusion sampler for short-term exposure.

For short-term exposure diffusive samplers used worldwide as passive samplers and with high measurement accuracy, the principle and structure of the sampler, the method of measuring gas pollutants in the environmental atmosphere, and the method of converting them to atmospheric concentrations are described as reference materials.
