ABSTRACT:
A collector3capable 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 filter7installed in a holder6having a discharge route12a. The sampling filter7contains 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 holder6from a flue duct25through a sampling pipe2and an introduction pipe8are collected and sampled while the sample gas being passed through the sampling filter7and the resulting sample gas from which the chlorinated organic compounds are removed is then discharged out to the outside through the discharge route12a.
