Abstract:
An X-ray analyzing apparatus which comprises:a source of X-ray for irradiating a surface of a sample in a slantwise direction;a detecting means for measuring an intensity of a secondary X-ray generated from the sample;a drive means for moving the sample;a plurality of field-limiting slits each having a slit size corresponding to the size of a measuring area of the sample;a selector means for selectively bringing the field-limiting slits into a path of travel of the secondary X-ray between the sample and the detecting means one at a time;a drive control means for controlling the drive means to move the sample according to the size of the measuring area of the sample to a position at which the intensity of radiation of a primary X-ray towards the measuring area of the sample attains a maximum value; anda selector control means for controlling the selector means to render only the secondary X-ray emanating from the measuring area of the sample to be incident upon the detecting means.
