What is Method 0040?

SW-846 Test Method 0040: Sampling of Principal Organic Hazardous Constituents from Combustion Sources Using Tedlar Bags

Method 0040 is designed, using gas sampling bags, for sampling principal organic hazardous constituents from combustion sources like hazardous waste incinerators. This non-isokinetic Method uses a constant or proportional sampling rate dependent upon the extent and variability of the emission flow rate (Method 2).

A representative sample is drawn from a source through a heated sample probe and
filter. The sample then passes through a heated 3-way valve and into a condenser where the
moisture and condensable components are removed from the gas stream and collected in a trap. The sample is collected in a Tedlar® bag held in a rigid, air-tight opaque container. The dry gas sample and the corresponding condensate are then transported together to a GC/MS. A mass spectrometer is most suited for the analysis and quantitation of complex mixtures of volatile organic compounds. The total amount of the analyte in the sample is determined by summing the individual amounts in the bag and condensate. A flow chart of the procedure is given at the end of this method.
