The raw material is cellulose fiber, which is more than 99% α-cellulose. Pure cellulose fibers are treated with hydrochloric acid and hydrogen fluoride to reduce the ash content to a low level of approximately 0.01%, allowing for highly accurate quantitative analysis. It is especially used for precise analysis.
