【 摘 要 】

A prototype semi-continuous monitor and associated particulate-free sample extraction probe have been developed for measuring the concentrations of SO{sub 3} and H{sub 2}SO{sub 4} in industrial flue gases. The monitor provides two measurements per hour for concentrations above 1 ppmv. The probe provides the capability of continuous operation while avoiding passing the sample through a layer of particulate and can be used as a probe for conventional controlled condensation measurements of SO{sub 3} and H{sub 2}SO{sub 4} emissions.
