Abstract

In order to simultaneously achieve suppression of an increase in manufacturing cost and a reduction in influence from precipitation of a sedimentary component on a measurement result, provided is an X-ray fluorescence spectrometric system including a rotation mechanism for rotating a sample cell and a speed control module for controlling a rotation speed of the rotation mechanism. The X-ray fluorescence spectrometric system operates in operation modes including an unstirred measurement mode and a stirred measurement mode. In the unstirred measurement mode, a detector executes measurement during rotation of the rotation mechanism at a constant speed under control of the speed control module. The stirred measurement mode includes a stirring period in which a liquid sample is stirred through rotation of the rotation mechanism at a varying rotation speed which is caused by the speed control module, and a post-stirring measurement period in which the detector executes measurement after the liquid sample is stirred. A liquid sample cell contains the liquid sample and includes a portion in which a cross-section of a containing space parallel to a lower surface is not a circle centered about a rotation axis of the sample cell.
