Interpretive Summary:

Technical Abstract: Four identical PM10 pre-separators, along with four identical low-volume (1m3 hr-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 sampler’s performance characteristics. The PM’s used in the chamber tests had mass median diameter (MMD’s) larger than 10 'm, whereas the PM emitted from oil pipe cleaning system for the field tests had MMD’s smaller than 10 'm. The co-located TSP and PM10 sampler testing results indicate that PM10 samplers over-sample when exposed to ambient PM having MMD’s 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 / under-sampling rates varied with the change of MMD and the PM loading (TSP concentration). The cut-points and slopes of the PM10 pre-separator changed with the change of MMD’s of inlet particulate matter (PM).
