Principle of energy dispersive X-ray fluorescence spectrometer

The electron layer is excited by high energy X-ray, which makes the electrons outside the nucleus transition, resulting in the secondary X-ray energy release. Because the energy released by different elements has different characteristics, the detection system measures the energy and quantity, so as to calculate the element content.

Main components

High voltage - light tube - detector and preamplifier - main amplifier - DPP - control module - communication module - display system, etc

The precious metals were analyzed and classified

At present, using XRF analyzer to analyze the chemical composition and determine the purity of precious metals has become a widely used, very popular and reliable method with the support of national standards. Compared with spark assay and chemical reagent test, XRF is a more rapid and economical method for the analysis of precious metals.

PM-450 XRF analyzer produced by jpspec provides users with a detection technology with convenient operation and high cost performance: it is not necessary to probe the detection tool into the material of the sample to be tested, and it will not damage the sample to be tested, so the alloy chemical composition information of the sample can be obtained, and the carat grade of the sample can be judged. Whether you are buying gold and other precious metals, or selling or producing jewelry, or manufacturing metals, or recycling waste metals, you need to master a fast method that can accurately determine the carat grade and the content of other precious metals and non precious metals, so as to effectively control the product quality and set a reasonable price in the first time.

PM-450 analyzer can quickly get accurate analysis results of various types of samples.
