Abstract
A calculating devicefor calculating the concentration of elements contained in a samplebased on the FP method is provided. The calculating deviceis operable to assume a concentration of unmeasured elements as far as unmeasured elements, of which fluorescent X-rays are not measured, are concerned, and, also, to utilize, in place of the secondary X-rays emanating from the unmeasured elements contained in the sample, scattered X-rays of the primary X-rays at least equal in number to the number of the unmeasured elements, of which concentrations are assumed, and including scattered X-rays of different wavelengths before they are scattered from the sample.
