Abstract:
An X-ray fluorescence spectrometer for measuring an intensity of secondary X-rays emitted from a sample as a result of excitation with primary X-rays, said spectrometer comprising:an r drive means for driving an r drive shaft to transport a sample holder in a circumferential direction about the r drive shaft between an irradiating position, at which the sample mounted in a sample holder is irradiated with the primary X-rays, and a delivery position at which replacement of the sample holder takes place and, also, for driving the r drive shaft at the irradiating position to thereby position a target area to be analyzed of the sample in the circumferential direction; and a &thgr; drive means having a function of driving a &thgr; drive shaft at the irradiating position to continuously rotating the sample holder about a center axis thereof and operable to drive the &thgr; drive shaft at the irradiating position to position the target area of the sample about the center axis; wherein the r drive shaft and the &thgr; drive shaft form a dual coaxial shaft assembly.
