Abstract
Four identical PM10 pre-separators, along with four identical low-volume (1 m3 h-1) total suspended particulate(TSP) samplers were tested side-by-side in a controlled laboratory particulate matter (PM) chamber. The four PM10 and fourTSP samplers were also tested in an oil pipe cleaning field to evaluate the PM10 samplers performance characteristics. ThePMs used in the chamber tests had mass median diameters (MMDs) larger than 10 .m, whereas the PM emitted from the oilpipe cleaning system for the field tests had MMD smaller than 10 .m. The co-located TSP and PM10 sampler testing resultsindicate that PM10 samplers over-sample when exposed to ambient PM having MMD larger than 10 .m aerodynamicequivalent diameter (AED) and under-sample when exposed to ambient PM with MMD smaller than 10 .m. Theover-sampling and under-sampling rates varied with the change of MMD and the PM loading (TSP concentration). Thecutpoints and slopes of the PM10 pre-separator changed with the change of MMD of inlet PM.
