Application of HPXRF for the Determination of Copper, Selenium, and Silver in Anode Slime Powder within the Copper Industry

This application note presents a solution for the quantitative analysis of copper, selenium, and silver in anode slime powder using a high-precision X-ray fluorescence elemental analyzer.

Application Overview

The high‑precision X‑ray fluorescence elemental analyzer is well‑suited for a range of industries, including geology and mining, steel metallurgy, hydrometallurgy, environmental soil analysis, and food safety. It enables rapid and accurate detection of process samples, and delivers reliable analytical performance for key elements such as copper, selenium, tellurium, and silver.

Technical Principles

The High-Precision X-ray Fluorescence Elemental Analyzer (HPXRF) utilizes Monochromatic Focusing Doubly Curved Crystal (DCC) optics, which monochromatize polychromatic X-rays from the source and effectively focus them onto the sample. This greatly enhances the instrument's signal-to-noise ratio. Upon monochromatization, elements in the sample emit characteristic X-ray fluorescence signals. These signals are collected and processed by a high-resolution Silicon Drift Detector (SDD), and the software's Fundamental Parameter (FP) algorithm calculates the elemental content in the sample.
