Measurements were carried out with a Johnas, an Andersen cascade impactor and a PM10 separator monted on a Tecora. The results were compared with each other and with the results of dust concentrations measured with a Tecora in accordance with ISO 9096. ...
Laboratory measurements were conducted to determine the impactor collection efficiency as a function of paricle size. Impactor cut points - the aerodynamic particle diameter exhibiting 50% collection efficiency - were 2.5 um (+- 10%) for the flat stage and 3.0 um for the cup stage. Collection efficiency curves for cascade (tandem) impactor ...
