1. for adsorbing the getter systems (10) of one or more of gases, it comprises:

  • -the polymer devices (11) poor to gas permeability upon adsorption, described polymer devices is selected from polyvinyl chloride (PVC), polystyrene (PS), poly-(methyl) methyl acrylate (PMMA), the copolymer of acrylonitrile-butadiene-styrene (ABS) (ABS), the cycloolefin of copolymerization, polysulfones, polyether sulfone (PES), copolymer with Kynoar, copolymer with poly-hexafluoro-isobutene, with poly copolymer, copolymer with poly-perfluor dimethyl dioxole, polyimides (PI), fluorinated polyimide, Merlon (PC), PET (PET), polysiloxanes and liquid crystal polymer (LCP), the polymer devices of described poor permeability demonstrates not higher than 1 * 10 -12m 3(STP) m -3bar -1m 2s -1permeability value, The powder (12) of-porous material that distributes in polymer devices, porous material is selected from natural or synthetic zeolite, silicalite, alumino-silicate, fullerene and metal organic frame;

    -activated the material (21 of tool aspect the one or more of gas of absorption, 21 `

    , 21 `



    , ...), it is characterized in that being present in the hole (20 of the powder disperseing at the activated material of tool aspect the absorption of gas in matrix, 20 `

    , ...) in, with, wherein gas upon adsorption is oxygen, the activated material of tool is selected from oxidable metal, the metal oxide that oxidation state is low, the salt with phosphite or phosphinate anion, with oxidable organic compound, wherein gas upon adsorption is carbon monoxide, the activated material of tool is selected from nickel, iron, olefine under lithium base organo-metallic compound exists, amine and ketone, wherein gas upon adsorption is carbon dioxide, the activated material of tool is the hydroxide of alkali metal or alkaline-earth metal,Wherein gas upon adsorption is nitrogen, and the activated material of tool is selected from lithium, barium, compd B aLi 4and porphyrin, or Wherein gas upon adsorption is water, and the activated material of tool is selected from epoxides;

    The organic molecule with two keys or triple bond;

    Alkali metal oxide, alkaline earth oxide, or the oxide of nickel, zinc and cadmium, and organic or inorganic acid anhydrides, and the compound that forms carbocation;

    Alkoxide;
