Determination
of Polychlorinated Dibenzo-p-dioxins and Polychlorinated Dibenzofurans
from Municipal Waste Combustors – USEPA Method 23 USEPA Method 23 is used to determine emissions of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) from stationary sources. Other semivolatile organic compounds (SVOCs) such as PAHs and PCBs may be determined using this method with appropriate analytical modifications. A sample is withdrawn isokinetically from the gas stream and collected in a sample probe, on a glass fiber filter, and on a packed column of adsorbent material (XAD-II resin). The PCDDs and PCDFs are extracted from the sample, separated by high resolution gas chromatography (HRGC), and measured by high resolution mass spectrometry (HRMS). |
