ABSTRACT:
The SO.sub.3, H.sub.2 SO.sub.4 content of a gas environment containing SO.sub.2 and H.sub.2 O is measured by cooling the gas to a temperature to convert SO.sub.3 in the presence of H.sub.2 O to H.sub.2 SO.sub.4 to effectively separate SO.sub.3, H.sub.2 SO.sub.4 from SO.sub.2 to permit the individual measurements of SO.sub.x (SO.sub.2 +SO.sub.3), SO.sub.2 and SO.sub.3, H.sub.2 SO.sub.4.
