X-Ray Fluorescence Spectrometer – Gas Proportional XRF Detector CGX-101 The X-Ray Fluorescence Spectrometer – Gas Proportional XRF Detector CGX-101 is a high-performance instrument designed for fast, accurate, and non-destructive analysis of precious metals. It is widely used in jewellery manufacturing, hallmarking centres, assay laboratories, precious metal refineries, and quality control applications. Utilizing advanced Energy Dispersive X-Ray Fluorescence (EDXRF) technology, the instrument provides reliable elemental analysis and gold purity testing without damaging the sample. 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), and Tin (Sn) in the jewellery industry. The Energy Dispersive X-Ray Fluorescence (EDXRF) technique relies on the detector and the detection circuit capability to resolve spectral peaks generated by different energy X-rays emitted when a primary X-ray beam strikes a metal alloy. The intensity of the emitted spectrum is proportional to the concentration of each element present in the sample. The spectrum is then processed using powerful computer software, which accurately calculates and reports the elemental composition of the sample. The XRF Gold Purity Tester consists of an X-ray tube, high-voltage power supply for the X-ray source, X-ray tube filters, X-ray fluorescence detector, processing electronics, system interface, and an external computer. A camera is incorporated into the system to allow users to view the sample directly on the computer screen for accurate positioning and testing.

Standard samples are analyzed to generate spectral intensity versus concentration calibration curves. These calibration curves are then used to evaluate the elemental composition of unknown samples with high accuracy. How to Get the Best Results from the XRF Spectrometer • Proper standardization and calibration of the equipment are essential for accurate results. • For intricate jewellery designs, testing at multiple points is recommended to obtain the most representative composition. • Ensure adequate warm-up time, a stable working surface, proper grounding, and an air-conditioned environment for optimum performance. • For powder samples, proper grinding minimizes scattering effects. • For solid samples, surface polishing helps reduce scattering and improves measurement accuracy. • Flat sample surfaces provide the most accurate testing results. • Due to differences in melting points, atomic structures, and manufacturing techniques, not all elements can be uniformly melted with noble metals.
