Performance characteristics of the 10 mm respirable mass sampler: Part II--coal dust studies. 1977

K J Caplan, and L J Doemeny, and S D Sorenson

The 10 mm cyclone respirable mass sampler was evaluated to determine the flow rate which best matched the BMRC and the LASL-ACGIH criteria, and to determine effects of pulsating flow, particle charge, mass loading, and sampler orientation. Part II, this paper, presents the work with coal dust. There is no significant difference between results obtained, for normal ranges of airborne dust concentration and size distribution, due to particle charge, sampler orientation or position (except upside down, which was not investigated), dust concentration, and ambient air velocity.
