X-ray fluorescent energy dispersive sulfur analyzer ASE-3
X-ray radiation of low duty X-ray tube converted by primary radiation filters excites the fluorescence radiation of atoms of the sample under examination. Radiation flows (primary radiation scattered on the sample and secondary fluorescence radiation) comes in proportional gas meter and sulphur atom fluorescence radiation (SKa) is separated from radiation with other energies by means of selective filters.
The strength of sulphur atom fluorescence radiation recorded by proportional gas counter is proportional to the sulphur concentration in the material under examination.
