The Principle of Energy Dispersive
X Fluorescence Spectrometer
High-energy X-ray stimulates atomic electron shell,the extranuclear electron of atoms will jump and secondary X-ray energy releases. Because the energy that different element releases possesses different characteristic. Detection system can measure the energy and quantity to calculate the elements content.
The Main Components
High Voltage-X-Ray Tube-Detector&Pre-Amplifier-Main Amplifier-DPP-Control Module-Communication Module-Display System, etc
Currently using XRF analyzer for composition analysis of precious metals and purity judgment has become a method of reliable performance, widely application and high popularity. Moreover XRF analyzers have the support of the national standard. Compared with fire assay method and chemical reagents test method, using XRF analysis of precious metals is a much more quickly, more economic and multi-element detection method.
Fluorescence spectrum analyzers that HongTuo Instrument produces provide a detection technology of convenient operation ,competitive price, stable and accurate performance. We don't need to put test tools into the tested sample materials, and do not damage the samples being measured, then we can obtain the metal elements information of jewelry. The whole testing process only takes couple of minutes. All the liquid, solid and powder samples are available.
