Abstract:
1. An X-ray analyzer comprising: a radiation source which irradiates a radial ray to an irradiation point on a sample; an X-ray detector which detects a characteristic X-ray and a scattered X-ray emitted from the sample and outputs a signal including energy information on the characteristic X-ray and scattered X-ray; an analyzer which analyzes the signal; a sample stage on which the sample is placed; a moving mechanism which moves the sample on the sample stage, the radiation source, and the X-ray detector relative to each other; a height measuring mechanism which measures a maximum height of the sample; and a control unit which adjusts a distance between the sample and the radiation source and a distance between the sample and the X-ray detector by controlling the moving mechanism on the basis of the measured maximum height of the sample.
