Data processor for fluorescent x-ray spectroscopy |
摘要 |
A data processor for fluorescent x-ray spectroscopy calculates theoretical x-ray intensity which is theoretically expected to be obtained by a fluorescent x-ray spectroscopy measurement of a standard sample with known composition by taking into account the effects of x-ray attenuation by the possible presence of an environmental gas along the optical path of the x-rays between the x-ray tube and the sample and between the sample and the detector. The element sensitivity for each of elements in the standard sample is obtained from this calculated x-ray intensity and the intensity actually measured and is stored in a memory. When a fluorescent x-ray spectroscopy measurement is carried out on an unknown sample, the sample is quantitatively analyzed, a theoretically calculated x-ray intensity obtained also by taking into account the effects of x-ray attenuation by an environmental gas is used together with the actually measured x-ray intensity and the element sensitivities stored in the memory.
