Abstract
The results of several research field studies were evaluated to estimate the precision and bias of various designated PM2.5 Federal Reference Method (FRM) samplers. Precision was favorable in these carefully conducted research studies where ali operational activities were strictly controlled, with an average coefficient of variation (CV) ranging from 2 to 6%. No significant bias was found between the method designations. Comparisons between the designated reference method samplers meet the EPA Equivalent Method Criteria for comparability except for one pair of samplers. In this instance, the y-intercept of the Andersen RAAS2.5-300 versus the Rupprecht & Patashnick Partisol-Plus 2025 was 1.07 μg/m3, slightly exceeding they-intercept 1.0 μg/m3 limit. Non-designated PM2.5 samplers demonstrated strong linear relationships when compared to reference method samplers; however, the comparisons presented in this analysis did not meet the EPA Subpart C criteria. These results indicate that the currently designated reference method samplers should allow precision and bias objectives to be achieved for the National PM2.5 Network.
