I. What Is a Metal Analyzer?

A metal analyzer is a scientific instrument that uses advanced analytical methods such as X-ray fluorescence (XRF) to determine the elemental composition of metals and alloys.

Beyond accurately identifying the proportion of elements such as Au, Ag, Cu, Ni, Zn, and Fe, this device serves as a powerful tool for testing the purity of gold and silver, verifying materials, and ensuring product quality control.

II. Operating Principle of XRF Metal Analyzers

XRF (X-ray Fluorescence Spectroscopy) is a qualitative and quantitative analytical technique used to determine the elemental composition of materials by measuring the fluorescent X-rays emitted from atoms when they are excited by high-energy X-rays.

Figure 1: Basic structure of an XRF metal analyzer

An XRF metal analyzer operates based on a well-established physical phenomenon: when a beam of X-rays irradiates a sample, the high-energy photons eject inner-shell electrons from the atoms. As outer-shell electrons move down to fill these vacancies, they emit secondary X-rays (fluorescent X-rays) with energies characteristic of each element. These secondary X-rays are then detected by a detector, converted into electrical signals, and processed by specialized software. The software analyzes the energy spectrum of the detected X-rays to identify which elements are present in the sample and determine the percentage composition of each element with high accuracy.
