Abstract: A zeolite membrane complex includes a porous support and a zeolite membrane formed on the support. In the zeolite membrane, a Si/Al ratio which is a molar ratio becomes larger as it goes from an interface portion with the support toward a membrane inner portion and the Si/Al ratio becomes smaller as it goes from the membrane inner portion toward a surface portion opposite to the support.

Abstract: A particle adhesion device includes: a holder; a chamber; a nozzle; an intake port; and a flow control member. The holder holds a filter substrate having a first end face and a second end face. The chamber is in communication with the holder and is arranged so that the first end face of the filter substrate faces a space in the chamber. The nozzle is arranged on an opposite surface of the chamber opposing to the first end face of the filter substrate, and can inject an aerosol containing particles toward the first end face of the filter substrate. The intake port is provided on the opposite surface of the chamber and can incorporate an ambient gas. The flow control member is arranged on the opposite surface provided with the intake port, and can control the flow of the ambient gas.
