Sampling device for air pollution analysis method, collection filter manufacturing method and sampling post-treatment method

摘要

The present invention relates to a sampling apparatus for analyzing air pollution, a method of manufacturing a collecting filter, and a post-sampling method, wherein an inflow impactor for crushing and injecting sampled air to be sampled into fine particles having a predetermined size and a uniform flow of the introduced sampled air. A gas component collecting part equipped with an air flow holder for guiding in a straight state, a plurality of collecting filters for adsorbing only gas components in the introduced sample air, and a particle component in the sample air passing through the gas component collecting part. And a particle component collecting part equipped with a plurality of filters for adsorbing the vacuum, and a vacuum pumping part pumped to allow a predetermined amount of sample air to flow within a predetermined time. Therefore, according to the present invention, a porous metal sheet filter can separate gas and particle components to collect contaminants in the air, thereby further improving sampling efficiency, and allowing particles and ions in spaces to be cleaned. The degree of contamination can be assessed fairly accurately.
