Product Introduction
The Energy-Dispersive X-ray Fluorescence (EDXRF) analyzer is a non-destructive elemental analysis instrument based on the principle of X-ray fluorescence. The instrument irradiates the sample with an X-ray tube; atoms in the sample are excited and emit characteristic fluorescent X-rays. An energy-dispersive detector (typically a silicon drift detector, SDD) then resolves the energy and intensity of each element, enabling qualitative, semi-quantitative, and quantitative elemental analysis of the sample. It is widely used for RoHS/halogen-free screening in the electrical and electronics industry, composition analysis of alloys and precious metals, coating thickness and composition analysis, and elemental inspection in fields such as minerals and building materials.
