Introduction
In modern industries, understanding material composition is critical for ensuring quality, performance, and compliance with regulations such as RoHS (Restriction of Hazardous Substances). XRF machines, which utilize energy dispersive X-ray fluorescence (EDXRF) technology, have become indispensable tools in achieving these goals. The LISUN EDX-2A XRF machine is a prime example of cutting-edge technology designed to provide reliable, accurate, and efficient material analysis.

This paper aims to delve into the features of the LISUN EDX-2A, highlight its applications in various industries, and demonstrate why it is a superior choice for RoHS testing and beyond.

Principles of XRF Technology

• What Is XRF?
X-ray fluorescence (XRF) is an analytical technique used to determine the elemental composition of materials. When a sample is exposed to high-energy X-rays, its atoms emit secondary (or fluorescent) X-rays. These emitted X-rays are characteristic of the elements present in the material.

• EDXRF Technology
The energy dispersive XRF (EDXRF) method involves measuring the energy and intensity of the fluorescent X-rays emitted. Unlike wavelength dispersive XRF (WDXRF), which relies on crystals to diffract X-rays, EDXRF uses solid-state detectors to analyze energy levels, making it faster and more adaptable.
