| Abstract |
Two sampling arrangements that allow four independent trains to sample simultaneously at the same point in the stack are described. These sampling arrangements have been used to obtain replicate particulate samples from stationary sources. Sixteen particulate sampling runs that used these sampling arrangements with four identical EPA Method 5 particulate trains determined that the magnitude of the within-run standard deviation was linearly related to the magnitude of the mean particulate concentration measured for that run. However, no such relationship was found between the within-run standard deviation and either the run sampling time or the total volume of gas sampled. The collaborative tests of the EPA particulate method (designated as method 5) were carried out at three different sources - a Portland cement plant, a municipal incinerator, and a coal-fired power plant. From a statistical analysis of the percent moisture in the stack determination, an estimate is made of the precision of the condensation technique used in the Method 5 sampling train. |
