In 1990, the Rupprecht and Patashnick (R&P) Series 1400a Ambient PM10 monitor was designated as a federal equivalent method sampler by the EPA. The sampler uses the Tapered Element Oscillating Microbalance (TEOM) method to measure the ambient concentration of particulate matter (PM). Due to the operational convenience of the sampler, more state air pollution regulatory agencies (SAPRAs) are relying on TEOM monitors for compliance purposes. Based on field data collected in the Texas Panhandle, the results of this paper demonstrate that concentrations measured by the R&P Series 1400a monitor are consistently greater than those measured by a federal reference method (FRM) sampler.
