In the present invention, a solution containing a target substance is atomized into a mist in an atomizer 1 to produce a mixed fluid of mist and air. In the collection of the mist from this mixed fluid, an air transmission membrane 51 of a pore size is used that transmits air but does not transmit the target substance contained in the mist. In the present invention, the mixed fluid is brought into contact with the primary surface of the air transmission membrane 51, and the pressure on the primary surface is made higher than the pressure on the secondary surface of the opposite side, whereby the air in the mixed fluid is let to pass through the air transmission membrane 51 to separate part or all of the air contained in the mixed fluid. |
