<p>PROBLEM TO BE SOLVED: To prevent contamination of organic matters or ions in an environmental air, etc., from coming in, by a method wherein active carbon, graphite carbon, a carbon molecular sheave, a molecular sheave, an organic matter attracting polymer, or a mixture thereof is sealed in the interior of a container as an organic matters and ions attracting material. SOLUTION: A main body 1 is a casing made of aluminum, and a sample inputting/outputting opening/closing door 2 is also made of aluminum. A metallized retaining tool 4 of a wafer 3 installed longitudinally internally is manufactured with a stainless steel, and in order to prevent wafers from coming into contact with each other, there is a corresponding trench in each of the wafers. In order to make airtight between the opening and closing type door 2 and the main body 1, a gasket made of aluminum with high purity is used as a packing 5, and the door 2 and the main body 1 are clamped and fixed to each other by a buckle 6. In an organic matters attracting material installation part 8, powdered active carbon fixed by two metal mesh plates made of stainless are filled. Thus, it is possible to prevent organic matter contamination by a container itself and the open air during holding or transport of a sample.</p> |
