1. An apparatus for concentrating and diluting a specific gas comprising:

  • a specific gas concentrating system including a chamber having filled therein a particle material for condensation and vaporization capable of selectively condensing the specific gas or having equipped therein a gas transmission member selectively transmitting other gases than the specific gas and a freezing machine that cools the specific gas fed to the chamber to a predetermined cool temperature; and

    a gas feeding and retrieving system having a feeding port feeding a gas containing plural gas species, a diluted gas retrieving port retrieving a gas containing the specific gas having been diluted, and a concentrated gas retrieving port retrieving a gas containing the specific gas having been concentrated;

    wherein the diluted gas retrieving part of the gas fed to the chamber is performed dilution of the specific gas by selectively condensing the specific gas on a surface of the particle material or the gas transmission member through cooling with the freezing machine or by selectively transmitting the other gases than the specific gas by the gas transmission member, andwherein the concentrated gas retrieving part of the gas fed to the chamber is performed concentration of the specific gas by vaporizing the condensed gas on the surface of the particle material or the gas transmission member through heating a surrounding of the concentrated gas retrieving part, thereby continuously retrieving the gas containing the specific gas having been diluted through the diluted gas retrieving part of the chamber or the gas containing the specific gas having been concentrated through the concentrated gas retrieving part of the chamber.
