Low temperature pre-concentrator comprising adsorption trap for chemical analysis

摘要

The present invention relates to an ultra-low temperature concentrator (1000) comprising adsorption traps for a chemical analysis, which comprises: a vacuum chamber (100); a refrigerant tube (200) which is installed in the vacuum chamber (100) and in which a refrigerant flows; a cooling plate (300) which is combined with the refrigerant tube (200); a first flow pipe (410) which is installed in the vacuum chamber (100) and in which the air flows; a second flow pipe (420) which is installed in the vacuum chamber (100) and into which the air, which is conveyed from the first flow pipe (410), flows; a first adsorption trap (430) which wraps around a certain area of the first flow pipe (410) to come in contact with the cooling plate (300), to convey cold air of the cooling plate (300) to the certain area of the first flow pipe (410), and to allow balance gas, which includes nitrogen and oxygen in the air, to be collected; a second adsorption trap (440) which wraps around a certain area of the second flow pipe (420) to come in contact with the cooling plate (300), to convey cold air of the cooling plate (300) to the certain area of the second flow pipe (420), and to allow greenhouse gases in the air to be collected; and a pair of heaters (600) which are respectively installed on the first adsorption trap (430) and the second adsorption trap (440). The present invention aims to provide an ultra-low temperature concentrator comprising adsorption traps for chemical analysis, which is able to concentrate at an ultra-low temperature and detect some greenhouse gasses which minutely exist in the air.
