Abstract The magnetite sample was determined by all-elements test method through taking good use of advantages of Shimadzu EPMA （electron probe micro-analyzer） in instrument configuration. In other words， all elements in magnetite including ultra-light oxygen was directly determined. Then the contents of variable valence elements were calculated according to the principle of electric neutrality balance. The characteristics of Lβ/Lα of FeO and Fe2O3 contents were verified by state analysis. The testing results were relatively satisfactory.

Key words： all-elements test ultra-light element variable valence element magnetite electron probe micro-analyzer
