XRF is used to detect and analyze noble metals like Gold ( Au), Silver (Ag), Platinum (Pt),Iridium (Ir), Osmium (Os), Palladium (Pd), Rhodium (Rh), Ruthenium (Ru), Copper (Cu), Zinc (Zn), Nickel (Ni), Cadmium (Cd), Iron (Fe), Cobalt (Co), Indium (In), Tin (Sn), in theJewellery Industry.
Energy Dispersive X-ray Fluorescence (EDXRF) technique relies on the detector and thedetection circuit capability to resolve spectral peaks due to different energy X-Rays emittedwhen a primary X-Ray beam strikes a metal alloy corresponding to different elements in thesample, intensity of the spectrum radiation proportional to the concentration of element.
The spectrum is then processed through the powerful computer software which calculatesand reports the various elements & their composition in the sample. XRF Gold Purity Tester consists of X-Ray tube, high voltage power supply for X-Ray source, X-Ray tube filters, X-Ray fluorescence Detector, processing electronics and system interface & an external computer. A camera is incorporated in the system to view the sample on the computer screen.
