  • Publication number: 20050121383
    Abstract: A collector 3 capable of collecting and sampling simultaneously various types of chlorinated organic compounds in both particulate and gaseous forms contained in a fluid and easy to extract the sampled chlorinated organic compounds therefrom includes a sampling filter 7 installed in a holder 6 having a discharge route 12a. The sampling filter 7 contains fibers and an inorganic binder for binding the fibers to one another and has a fluid-permeability. Various types of the chlorinated organic compounds such as dioxins and coplanar PCBs in both particulate and gaseous forms contained in a sample gas flowing into the holder 6 from a flue duct 25 through a sampling pipe 2 and an introduction pipe 8 are collected and sampled while the sample gas being passed through the sampling filter 7 and the resulting sample gas from which the chlorinated organic compounds are removed is then discharged out to the outside through the discharge route 12a.
