Abstract
One aspect of the present teachings includes a separation membrane arranged in a hollow case. A particular component concentration chamber and a particular component dilution chamber are arranged in series in the hollow case. The particular component concentration chamber is capable of increasing concentration of the particular component by allowing permeation of the particular gas through the separation membrane. The particular component dilution chamber is capable of increasing concentration of the particular component by not allowing permeation of the particular gas through the separation membrane. The particular component concentration chamber and the particular component dilution chamber are configured such that only a gas containing the particular component and permeated through the separation membrane or only a gas containing the particular component not permeated through the separation membrane in one of the chambers disposed on an upstream side (i.e., the side of the inlet port) can flow into the other of the chambers.
