Zusammenfassung:	To provide an apparatus for generating formaldehyde monomer vapor.SOLUTION: An apparatus for generating a desired gas is provided. The apparatus includes an effusion tube comprising a first zone and a second zone. The first zone includes walls of micro-porous metal tube, and a closed end. The second zone includes non-porous metal tube, and an open end. The two-zone effusion tube is fixed to an inside of a larger cylindrical metal jacket with gas entry and exit ports at opposite ends, the cylindrical metal jacket allowing a gas to flow over an outside of the effusion tube. The effusion tube is configured to contain a matrix comprising media containing a parent compound and inert media. Also provided is heating means for heating the effusion tube thereby generating a desired gas which exits the open end of the metal jacket.SELECTED DRAWING: Figure 8 【課題】ホルムアルデヒドモノマー蒸気を発生させるための装置を提供する。【解決手段】所望のガスを発生させる装置が提供される。装置は第１の領域および第２の領域を含む流出管を含む。第１の領域は微孔質金属管の壁および閉鎖端部を含む。第２の領域は非孔質金属管および開放端部を含む。この２領域流出管は、両端部にガス入口ポートおよびガス出口ポートを有するより大きな円筒状金属ジャケットの内側に固定され、円筒状金属ジャケットは流出管の外側の上をガスが流れることを可能にする。流出管は、親化合物を含有する媒体と、不活性媒体とを含む母材を含有するように構成される。流出管を加熱し、それにより金属ジャケットの開放端部を出る所望のガスを発生させるための加熱手段。【選択図】図８
