Description

Technical Field

[0001] The utility model relates to the technical field of gas sampling, in particular to a full-automatic atmospheric particle sampling device. Background Art

[0002] Comprehensive monitoring of ambient air can not only improve the supervision and protection of the atmospheric environment, but also provide important data support for air quality management, weather forecasting, health risk assessment and scientific research. Most of the existing technologies are for the collection of gas, by collecting particulate matter in the gas, but there is a lack of sampling devices for only atmospheric particulate matter. The number of particulate matter in a certain volume of gas is limited, and a large amount of gas needs to be collected to collect atmospheric particulate matter that meets the detection needs. Collecting a large amount of gas requires a large number of gas cylinders, which are inconvenient to carry and transport. Therefore, it is necessary to design a sampling device that only collects atmospheric particulate matter from the atmosphere, without collecting a large amount of gas, to meet the needs of sampling and detection.
