A one-week study was conducted in August 1979 to evaluate the comparative ability of representative aerosol sampling systems to monitor fine particulate sulfur and sulfate concentrations periodically in situ. Participants in the study operated their samplers simultaneously in the same location for the duration of the study. Samplers tested included five modified flame photometric detection instruments and two dichotomous samplers, including one sampler designed to yield near-real-time sulfur concentrations from on-line, wavelength dispersive X-ray fluorescence analysis of the fine particle filter substrate. All but one of the samplers were operated from a common duct located within the same laboratory; the other was operated on the roof of the building.
