Patent abstract
A calculating device 10 for calculating the concentration of elements contained in a sample 13 based on the FP method is provided. The calculating device 10 is 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.
