Determination of polychlorinated dioxins and furans involves automatically calculating total amount of dioxins and furans as parameter, preferably as toxicity equivalent

摘要

Determination of polychlorinated dioxins and furans involves automatically removing sample gas from a gas stream, and collecting compounds for subsequent determination. The total amount of polychlorinated dioxins and furans is automatically calculated from the result of this determination as a parameter of the whole group of compounds, preferably as a toxicity equivalent. Determination of polychlorinated dioxins and furans involves automatically removing sample gas from a gas stream over a period of 1-72 hours, preferably 6-24 hours, collecting compounds for subsequent determination by adsorption or absorption, enriching, and determining the compounds selected from tetra-, penta- and/or hexa-chlorinated dibenzo-p-dioxin and/or dibenzofuran optionally after desorption. The total amount of polychlorinated dioxins and furans is automatically calculated from the result of this determination as a parameter of the whole group, preferably as a toxicity equivalent. An independent claim is also included for a device for carrying out the above process.
