Abstract The report describes an investigation of the needs and available techniques for in-stack PM-10 sampling. Discussion includes the conceptualization, development, documentation, and testing of two candidate methods. The first method, Constant Sampling Rate (CSR), is a procedural approach which adds particle size separation to sampling hardware that has been widely used in EPA Methods 5 and 17 but modifies the sampling protocol to accomplish the PM-10 objectives. The second method, Exhaust Gas Recycle (EGR), is an equipment approach which accomplishes the PM-10 objectives by using a modified sampling train to implement the concept of exhaust gas recirculation. Six field studies indicated that these techniques were practical and compared well with one another and with more labor-intensive approaches. Laboratory investigations with monodisperse aerosols indicated that commonly used geometries for sampling nozzles could cause a decrease in the particle size out of a closely coupled inertial sizing device. Nozzle geometries were also found which eliminated the observed shifts in particle size cut.
