Zusammenfassung:The step sampling apparatus of the sampler of the invention is characterized by that the superior limit of the respiratory dust size is 10 micron, that a reinforced glass fiber filter paper with an oil coating is used as the capturing plane, and that the support and holder for the capturing plane is dismountable. A coating tool is specially designed for coating on the capturing plane conveniently and reliably. So, the measuring accuracy should be improved and the error of main dust concentration measured should be in permissible range as the samples is used.
