METHOD AND DEVICE FOR TAKING SAMPLES FROM EXHAUST GASES

摘要

The invention relates to a method for taking samples from exhaust gases that contain substances of medium and low volatility, especially polychlorinated dibenzo(p)dioxins and polychlorinated dibenzo(p)furans, in a gas, solid or aerosol phase. A partial gas flow is deviated from the exhaust gas and is passed across a dust filter cartridge and then across an adsorber cartridge. According to the inventive method, it is not required to treat the three different partial samples in a laboratory to give a single sample and to determine its total content of the substances to be examined (dioxins and/or furans).
