Evaluation of the 10-mm Nylon Cyclone for Sampling Respirable Talc

摘要

The efficiency of a 10 millimeter nylon cyclone for sampling respirable talc was evaluated. A fluidized bed aerosol generator was employed to generate the refined yellowstone talc used in the study. Particles larger than respirable size were also used. The authors conclude that although the talc build up did not significantly alter the fraction of the dust collected on the filter, further measurements are needed to determine if the size distribution was altered. They recommend that the potential bias in weighing due to the collection of talc on the cassette walls should also be studied.
