美国SKC IMPACT采样头
SKC单极冲击器专为PM10,可吸入颗粒物。环境中PM(10-2.5)有效收集，采样流速设置为10L/mint通过冲击器，较大的颗粒通过47MM过滤器被一次性撞击盘收集，去除容易受外界影响的过滤盒，容易更换设置，撞击盘适合插入磁带的顶部，影响高流量需求，提供低水平的灵敏度，提高采样效率。

The parented SKC IMPACT single-stage inertial impactor is designed for the efficient collection of PM10,PM2.5,or PM Coarse(10-2,5)in ambient air. A sampling pump operating at 10L/min draws PM through the impactor;larger particles are captured on a disposable pre-oided impaction disc while samller particles collect on a 47-mm filter. IMPACT media changes are as easy as removing the filter cassette and replacing it with one already loaded. The impaction disc fits into the top of the cassette. IMPACT'S higher flow rate requirement provides increased sensitiveity for low levels of PM.For sampling efficiency date。
