Abstract	本发明公开了一种PM10单级大气采样切割器，所述PM10单级大气采样切割器大致为圆柱形；包括切割口盖层、冲击咀层、冲击板层、滤膜收集层、气态有机污染物收集层及出气层，所述切割口盖层、冲击咀层、冲击板层、滤膜收集层、气态POPs收集层及出气层依次密封串接；所述冲击咀层包括冲击咀及冲击咀板，所述冲击咀等距排列并垂直插入所述冲击咀板形成环状圈，所述冲击咀数量为6~8个，所述冲击咀为管状；所述冲击板层设有冲击板，所述冲击板为环形凹槽。采用本发明，突破了以往空气采样器均为中小流量的特点，300L/min的流量设计标准可以满足POPs采样需求，使得切割器的切割粒径更加精确，目标颗粒物在惯性冲击力切割下达到精确分层的目标。
