|Sulfur trioxide in the gaseous form is not indicated, but in the presence of atmospheric humidity this forms sulfuric acid aerosols, which are indicated. Soluble sulfates and other aerosol forming acids are also indicated but with different sensitivities. It is impossible to measure sulfuric acid in the presence of these substances.|
