Commercially available high-volume PM10 samplers were intercompared at a site in Phoenix characterized by high concentrations of coarse particles. Over a 21-day period, SierraAndersen 321A (SA 321A) samplers gave PM10 measurements 58% higher than the Wedding IP10 (WED) samplers and 16% higher than a SA 321A sampler that had an oil coating on the internal impaction surfaces of the inlet. WED samplers that were subjected to a simple brush cleaning procedure after each sampling period gave PM10 results 16% higher than the WED samplers not subjected to cleaning. The oiled SA 321A sampler gave PM10 values 15% higher than the cleaned WED samplers. The results demonstrate that the SA 321A overestimates PM10 when sampling in an environment with high coarse particle concentrations. The over collection results from pass-through of large particles, and can be minimized by oiling the internal impaction surfaces of the inlet. The WED sampler underestimates PM10 after several days of sampling in such an environment.
