Abstract |
The report describes results of laboratory and field work related to inertial particulate size classifiers (impactors and cyclones). The impactor work deals largely with non-ideal behavior of impactors and problems encountered in field testing. Preparation and handling procedures for using glass fiber impaction substrates are discussed, together with problems resulting from SO2 reactions with certain types of glass fiber filter media. The results of a brief series of tests of electrostatic effects in impactor sampling are described: they indicate that these effects can be substantial under some circumstances. Design and calibration data are given for two series cyclone size devices: one designed to operate at a flowrate of 140 liters/minute (5 cfm); and the other, at 28 liters/minute (1 cfm). Each provides three size fractionation points in the 0.5 to 10 micrometer size interval. The cyclone systems permit collection of larger quantities of size fractionated particulates and are somewhat easier to use than are impactors. |
