The analyzer operation principle is based on the excitation of atomic fluorescence radiation of substance sample by X-ray tube radiation. Fluorescence emission can be decomposed in spectrum by Cauchois method.
Fluorescence radiation focused by the analyzing crystal of the determined element and the line of standard are allocated onto the Rowland circle. Then they are recorded by turns by the X-ray detector. Intensity of fluorescence radiation registered of a certain wavelength is directly proportional to the mass fraction of a chemical element in the substance tested.
Distinctive scopes of application
- Geology and mining industry:
• determination of rock and ore composition;
• determination of concentrates composition. - Environmental safety:
• determination of Co, Ni, Cu, Zn, Ga, As, Rb, Sr, Ba, Pb in soils, sediments and rocks at ppm contents. - Determination of uranium and new advanced nuclear fuel thorium in rocks, ores and technological products in a wide range of concentrations from 10-4% and above.
- Determination of uranium in rocks, ores and products of their processing by X-ray fluorescence measurements is carried out according to the procedure No.420-РС developed by VIMS.
