Determination
of Particulate Matter Emissions from Stationary Sources – USEPA
Method 5B USEPA Method 5B is used to determine nonsulfuric acid particulate matter from stationary sources. Particulate matter is withdrawn isokinetically from the source and collected on a glass fiber filter maintained at a temperature of 160 ± 14 °C (320 ± 25 °F). The collected sample is then heated in an oven at 160 °C (320 °F) for 6 hours to volatilize any condensed sulfuric acid that may have been collected, and the nonsulfuric acid particulate mass is determined gravimetrically. |
