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.
