硫黄除去材料、並びにこれを用いた精製カラム及び有機物質分析の前処理方法

摘要

A mixture of an inorganic filler and inorganic particles that have a metal that reacts with sulfur on at least parts of the surfaces thereof is used as a sulfur-removing material that is less expensive than silver-nitrate silica gel and exhibits high sulfur-removal effectiveness. A pretreatment for organic-matter analysis is performed in a purification column using said sulfur-removing material.
