Abstract

The performance of a modified impinger is described. Laboratory and limited field studies found that the modification made the device relatively spill-proof. In addition, the collection efficiency of the spill-proof impinger was compared to the standard midget impinger. For particles larger than 0.8 micrometer equivalent aerodynamic diameter, the impaction efficiencies of the two devices were found to be identical. However, the capture efficiencies of the two devices were not always found to be equivalent. In three tests, the modified impinger collected proportionately more material than the midget impinger. In three other tests, the capture efficiencies of the two devices were found to be equivalent.

摘要

描述了一种改良撞击式采样器的性能。实验室研究和有限的现场研究发现，这种改良使该装置相对防溢出。此外，将防溢出撞击式采样器的收集效率与标准小型撞击式采样器进行了比较。对于空气动力学等效直径大于0.8微米的颗粒，发现两种装置的撞击效率相同。然而，并不总是发现两种装置的捕获效率相当。在三项测试中，改良撞击式采样器收集的物质比小型撞击式采样器按比例更多。在其他三项测试中，发现两种装置的捕获效率相当。
