The status of chemical analysis by X-ray fluorescence has developed from that of a laboratory curiosity in the decade 1940–50 to its current position as an almost universal method with, according to a recent estimate, over 8000 spectrometers in use throughout the world.

The intensification of X-Ray fluorescent images
Electrical Engineering, 1951Two experimental models of devices for the intensification of X-ray fluorescent images were put into use in September 1950. These devices have a brightness amplification slightly over 100 times and enable detection of a 3-per cent thickness difference.

A number of different X-ray fluorescence instruments are in routine use: (i) Crystal dispersion, tube excitation, sequential counting. (ii) Crystal dispersion, tube excitation, simultaneous counting. (iii) Crystal dispersion, electron excitation. (iv) Non-dispersive, Ross filter, radioisotope excitation.

X-Ray fluorescence (XRF) is an emission spectroscopic method for the qualitative identification and quantitative determination of elements. With few exceptions, XRF provides no information concerning the chemical species in which the sought element is found.

Although X- ray fluorescence technique, in principle, belongs to an atomic method, it is often cataloged into nuclear discipline, especially those based on nuclear facilities, e.g. accelerator, isotopic sources and radiation detection spectrometry.
