| Abstract: | Discussions have been made for the detection limits (DL) of X-ray flourescence analysis and formulas for DL calculation have been derived from the statistic error theory of intensity measurements in various correction methods of backgrounds and matrix effects. The conclusions from this paper could be used as the roles for selection of background and matrix correction methods and optimization of experiment conditions for the purpose of the lowest DL. |
