Performance characteristics of a low-volume PM10 sampler Conference Paper uri icon

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 four TSP samplers were also tested in an oil pipe cleaning field to evaluate the PM10 samplers' performance characteristics. The PMs used in the chamber tests had mass median diameters (MMDs) larger than 10 m, whereas the PM emitted from the oil pipe cleaning system for the field tests had MMD smaller than 10 m. The co-located TSP and PM10 sampler testing results indicate that PM 10 samplers over-sample when exposed to ambient PM having MMD larger than 10 m aerodynamic equivalent diameter (AED) and under-sample when exposed to ambient PM with MMD smaller than 10 m. The over-sampling and under-sampling rates varied with the change of MMD and the PM loading (TSP concentration). The cutpoints and slopes of the PM10 pre-separator changed with the change of MMD of inlet PM. 2005 American Society of Agricultural Engineers.
