Development of personal diesel aerosol sampler design and performance criteria.
Min Eng 1991 Feb; 43(2):232-236
The U.S. Bureau of Mines and the University of Minnesota have developed design and performance criteria for a personal diesel exhaust aerosol sampler for underground coal mines. These are based on the premise that size can be used to separate diesel exhaust aerosol, which is mostly submicrometer in size, from coal dust aerosol, which is mostly greater than 1 um in size. The sampler has three stages: a respirable aerosol preclassifier, a 0.8-Um aerodynamic diameter inertial impactor to collect mineral dust, and a final filter to collect the diesel aerosol. Using a sample flow rate of 2 l/min and gravimetric analysis to within 0.1 Mg, the measure sub-0.8-Um diesel aerosol has an a priori limit of detection of 0.3 Mg/m3.
