What is Method 8?

Determination of Sulfuric Acid Mist and Sulfur Dioxide Emissions from Stationary Sources

A gas sample is extracted isokinetically from the stack. The H2SO4 and the SO2 are separated,
and both fractions are measured separately by the barium-thorin titration method.

U.S. EPA Reference Method 8 was originally developed to test emissions from sulfuric acid plants but has been adapted to sample emissions from many sulfur dioxide sources.

For more information and documents about Method 8, please consult the EPA's Method 8 webpage.
