Abstract
An operation for a chemical of indefinite form is managed so that operation record of the chemical is traceable. An IC tag () is attached to various containers (toc ) each holding a chemical, and a chemical ID to identify the chemical held in each of the containers (a toc) is stored in the IC tag (). When an operation involving a mass change or a change of composition information is carried out, such as apportioning, mixing, reacting, and separating, while the containers (a toc) serve as receivers of the chemical, a record management apparatus () newly generates a chemical ID, and a IC tag terminal () updates the chemical ID in the IC tag () to the new chemical ID. In addition, the record management apparatus () manages a correspondence between the chemical ID stored in the IC tag () (old chemical ID) and the chemical ID newly stored in the IC tag () (new chemical ID).
