<p>Energy dispersive X-ray fluorescence (ED-XRF) spectrometer was built in the laboratory with low wattage X-ray tube and silicon drift detector using a 3D printer. SUS 304 and 316L stainless steels were measured by the ED-XRF spectrometer and a sequential type inductively-coupled plasma atomic emission spectrometer (ICP-AES). The results of quantitative analysis obtained by the fundamental parameter (FP) program developed by the authors were compared with the ICP-AES results, and concluded the following three points.</p><p>(1) The FP method is a first principles method to theoretically calculate the concentration of elements using XRF. The accuracy and precision are satisfactory but inferior to the calibration curve method.</p><p>(2) The representative accuracy and precision in SUS 304 quantification are expressed as 18.3±0.08% for Cr and 18.1±0.01% for Ni. These values are comparable to the accuracy and precision of ED-XRF. Therefore the FP method is suitable for the ED-XRF analysis; the calibration curve method (dj method) is highly precise and accurate, and thus suitable for wavelength dispersive (WD) XRF method.</p><p>(3) Though it is said that the FP databases should be improved in order to increase the accuracy, the FP database improvements have not been effective.</p>
