【Information about the products is renewed】

Idea International has so far provided element-analysis data by TOFMS to assure encapsulation of Lithium ion inside the fullerene and purity of the products. As the results of recent R&D activities, it has become clear that an analysis by NMR can provide more accurate data to judge whether Li ion is encapsulated or circumscribed as well as purity of the products. Accordingly we provide herewith

purity data derived from NMR analysis which leads to more accurate values/figures.
