The report describes a transportable sampling apparatus designed to sample incineration sources at municipal and hazardous waste disposal facilities, and to provide non-contaminated samples of condensable materials. The sample gas, at a flowrate of 10 cubic feet per minute (c fm), passes through a modified Source Assessment Sampling System (SASS) cyclone and is then diluted with clean air at 100 cfm by a novel, perforated cone assembly. Rapid uniform dilution takes place through the vigorous mixing of the sample and clean air streams in the dilution chamber. The resultant gas, cooled to about atmospheric conditions, is passed through a mixing section that provides a residence time of about 3 seconds. The resulting aerosol particles are collected on a Teflon-coated glass-fiber filter. These solids, along with those collected in the cyclone, are subsequently provided for chemical and biological assay analysis.
