A guidance manual, prepared under EPA contract, was written to catalogue the methods used to measure and report total organics data from stationary source emissions. The guidance manual identifies specific techniques to determine the total organics sampled from stationary combustion sources. To generate a value for total organics, organics data from three specific boiling point/vapor pressure classes are combined: light hydrocarbons and volatile organics (measured using Field Gas Chromatography and Purge and Trap Gas Chromatography), semivolatile organics (measured using a total chromatographic organics method), and nonvolatile organic compounds (measured using a gravimetric analysis method). The methods for measuring and reporting the individual parameters are discussed in detail in the guidance manual.
