Principles and Limitations of Electron Probe Microanalysis] that each element in the periodic table is characterised by a relatively simple X-ray spectrum. The basic experimental arrangement is outlined in Fig. 1. An electron beam (.) of moderate energy (5–40 kV) is directed on to the sample (.) to be investigated, in vacuo, and the X-rays (.) emitted from

The Measurement of Total Mass per Unit Area and Elemental Weight-Fractions along Line Scans in Thin servations of characteristic line intensities with simultaneous observations of the bremsstrahlung. The bremsstrahlung counting rate also provides a means to subtract background instantaneously from a characteristic peak, with no need for background measurements off the Bragg angle, thus permitting
