Abstract:
A fluorescent X-ray analyzing apparatus which comprises:detecting means for detecting and analyzing, by means of a detecting means, fluorescent X-ray emitted from at least one predetermined target area of a sample to be analyzed as a result of excitation of such target area with a primary X-ray;said detecting means comprising a wavelength dispersive type detecting means including a spectroscope and a first detector, and an energy dispersive type detecting means including a second detector of an energy dispersive type; andwherein an angle formed between a first path of travel of the fluorescent X-ray from the target area towards the spectroscope and a surface of the sample is equal to an angle formed between a second path of travel of the fluorescent X-ray from the target area towards the second detector of the energy dispersive type and a surface of the sample, but said second path of travel of the fluorescent X-ray is shorter than said first path of travel of the fluorescent X-ray.
