the federal reference method PM2.5 sampler, and the improve sampler Performance test results from the cascade impactor

Performance testing was conducted on a Graseby Andersen 8-stage cascade impactor to evaluate it's accuracy. Performance testing was also conducted of a Graseby Andersen federal reference method(FRM) PM2.5 sampler and an IMPROVE PM2.5 sampler. These two samplers operate on very different principals; the FRM sampler uses jet impaction preseparators and the IMPROVE uses a cyclone preseparator. PM2.5 concentrations as measured by the FRM and IMPROVE samplers as well as those determined by the Coulter Counter Multisizer from the TSP and PM10 samplers, were not found to be significantly different, when statistically analysed.
