in coal, but cannot yet determine the composition of the organic components. the sample required for fluorescence analysis is about g. it must be ground to an extremely fine particle size approximately mm or less, in order to minimize and to render less variable the absorption of the fluorescence x rays
of a typical ash. a suggested composition is as follows: % potassium carbonate, % sodium chloride, % calcium carbonate, % magnesium carbonate, and % germanium oxide. prepare working curves by adding graduated amounts of elements to portions of this salt mixture. x-ray fluorescence analysis. when x rays...
