620 METHOD 6A - DETERMINATION OF SULFUR DIOXIDE, MOISTURE, AND CARBON DIOXIDE FROM FOSSIL FUEL COMBUSTION SOURCES NOTE: This method does not include all of the specifications (e.g., equipment and supplies) and procedures (e.g., sampling and analytical) essential to its performance. Some material is incorporated by reference from other methods in this part. Therefore, to obtain reliable results, persons using this method should have a thorough knowledge of at least the following additional test methods: Method 1, Method 2, Method 3, Method 5, Method 6, and Method 19. 1.0 Scope and Application. 1.1 Analytes. Analyte CAS No. Sensitivity SO 7449-09-05 3.4 mg SO /m3 2 2 -7 3 (2.12 × 10 lb/ft ) CO2 124-38-9 N/A H O 7732-18-5 N/A 2 1.2 Applicability. This method is applicable for the determination of sulfur dioxide (SO ) emissions from 2 fossil fuel combustion sources in terms of concentration (mg/dscm or lb/dscf) and in terms of emission rate (ng/J or 6 lb/10 Btu) and for the determination of carbon dioxide (CO ) concentration (percent). Moisture content (percent), 2 if desired, may also be determined by this method. 621 1.3 Data Quality Objectives. Adherence to the requirements of this method will enhance the quality of the data obtained from air pollutant sampling methods. 2.0 Summary of Method. 2.1 A gas sample is extracte
