A continuous sampling and clean-up device for the determination of PCDD/PCDF in stack gas of incinerators and thermal processes had been described recently. Contamination effects of PCDD/PCDF at the inner surface of the sampling device caused by the adsorption/desorption equilibrium restoration were found to be the major problem for continuous operation of the device because they lead to false emission...
On the basis of standardized methods a continuous measuring method for the determination of PCDD/PCDF in stack gas of incinerators and thermal processes was developed. Significant time saving simplifications were performed by reducing the sampling fractions to the condensate fraction and selecting an indicator isomer of the 2,3,7,8-chlorinated congeners. The deviation caused by the simplification...
