Gas phase decomposition method, analysis method, quality control method, manufacturing method, and container

摘要

The present invention pertains to a vapor phase decomposition method for preventing contamination of a decomposed organic material by a decomposition fluid-derived metallic impurity and/or non-metallic impurity. The vapor phase decomposition method comprises: a preparation step in which the organic material and a decomposition fluid that decomposes the organic material are housed inside a sealed container such that the organic material and the decomposition fluid do not come in contact; and a decomposition step in which the sealed container is pressurized by heating the interior thereof, and the organic material is decomposed by decomposition fluid gas which is decomposition fluid that has vaporized.
