Research on Application and Performance of Energy Dispersive X-Ray Fluorescence Spectrometer for Gold Machine Tester

Abstract:

Introduction

Gold is widely used in jewelry, investment, industry and finance. Its purity, alloy ratio and impurities directly determine product value. Traditional detection methods such as fire assay and acid testing are destructive, inefficient and dangerous, which cannot meet modern testing requirements.

Gold machine tester based on X-ray fluorescence technology can identify elements and calculate content quickly without damage. LISUN EDX-2 series spectrometer integrates high-performance hardware and can be used as a professional gold machine tester. This paper studies its principle, parameters, testing process and application advantages.

Working Principle of Gold Machine Tester

Core Principle
EDX-2A, as a gold machine tester, uses energy-dispersive X-ray fluorescence technology. When X-rays irradiate the sample, inner electrons are excited to jump, and outer electrons fill the holes, releasing characteristic X-rays. Different elements have different characteristic energies, so the instrument can identify elements and calculate their content by analyzing spectral intensity.

LISUN EDX-2A Structure
LISUN EDX-2A is a desktop non-vacuum spectrometer with high-stability X-ray tube, Si-pin detector, HD camera and intelligent analysis software. It requires no sample pretreatment and supports solid, powder and block samples. It is widely used in gold machine tester, RoHS detection, elemental analysis and coating thickness test.
