The determining factors of a good analysis by x‐ray fluorescence are discussed, emphasizing the importance of the geometrical arrangement, especially the excitation‐source to analysis‐material distance. The variation of the peak area of the K α x‐ray of Fe is evaluated as a function of the distance. Precautions are given for the analysis of low concentration samples as well as for obtaining the relative concentration of an element in a specific material or organ.
