It comprises two procedures for the final determination of titanium, one of them relying on spectrophotometry and the other on flame atomic absorption spectrophotometry. The limits of the determination depend on the amount of sample taken (<span class=\"xref\">8.1<\/span>).<\/p>\n<div class=\"non-normative-note\">\n<div class=\"note-label\">\n  NOTE\n <\/div>\n<p>The method is designed for the determination of titanium dioxide.
