A laboratory and field evaluation of a sulfate measurement method has been conducted. During the evaluation, the effects of probe plug material, isopropanol, and flue gas metals were investigated for the possible oxidation of SO2 during sampling. Simultaneous field samples were collected in order to determine the effects of both quartz and pyrex probe plugs. The measurement method, when used to measure sulfate emissions from residual fuel fired boilers, was found to be repeatable and free of interferences due to SO2 oxidation. The sulfate collection efficiency of a sampling train with a pyrex probe plug was found to be slightly greater than an identical sampling train with a quartz probe plug.
