Abstract

In a preliminary measurement, spectrums obtained by detecting characteristic X-rays emitted from preliminary measurement points are transmitted to a spectrum processing unit (20) via a noise filter unit (22). In a main measurement, a spectrum obtained by detecting characteristic X-rays emitted from a main measurement point is transmitted to the spectrum processing unit (20) by bypassing the noise filter unit (22). The noise filter unit (22) includes a machine learning type filter constituted of a CNN or the like. In a learning process, teacher data are generated using artificially-generated noise.
