Gas Analysis for the Determination of Dry Molecular Weight
This method is applicable for the determination of CO2 and O2 concentrations to determine dry molecular weight of an effluent gas stream of a fossil fuel combustion process or other process.
Determination of Oxygen (O2) and Carbon Dioxide (CO2) in Stack Gas, (Instrumental Analyzer Procedure)
Method 3A is a procedure for measuring oxygen (O2) and carbon dioxide (CO2) in stationary source emissions using a continuous instrumental analyzer.
Gas Analysis for the Determination of Emission Rate Correction Factors or Excess Air
This method is applicable for the determination of O2, CO2, and CO concentrations in the effluent from fossil-fuel combustion processes for use in excess air or emission rate correction factor calculations. Where compounds other than CO2, O2, CO and nitrogen (N2) are present in concentratios sufficient to affect the results. This method does not apply to sources that (1) remove CO2 or O2 through processes other than combustion, (2) add O2 (e.g., oxygen enrichment) and N2 in proportions different from that of air, (3) add CO2 (e.g., cement or lime kilns), or (4) have no fuel factor, F0, values obtainable (e.g., extremely variable waste mixtures).
Determination of CO2, CH4, N2. and O2, from Stationary Sources Utilizing Gas Chromatography
This method applies to the analysis of CO2, CH4, N2, and O2 in samples from municipal solid waste landfills and other sources when specified in an applicable report.
