Abstract: An atmospheric sampling device is the primary equipment required for studying atmospheric pollutants; it collects various types of atmospheric particles, including organic and inorganic pollutants. However, at present, atmospheric samplers are mainly self-developed and modified for land use. Given the particularity of ship environmental conditions, there are certain risks involved in the application of such equipment on board. Therefore, researchers of the Xuelong 2 independently designed and made a new type of marine dual-channel large-flow sampling device. This sampler not only collects large-volume solid phase extraction columns, but also is compatible with other gas particle collections and historical data. It was successfully used during the 36th Chinese National Antarctic Research Expedition and the 11th Chinese National Arctic Research Expedition.
