Overview

Nondestructive Precious Metals Assay and Karat ID

XRF is a widely used, proven, and accepted method of chemistry analysis and determination of purity and fineness of precious metals. XRF analysis is a multi-elemental testing alternative that is quicker and less expensive than fire assay and chemical tests. XRF provides on-the-spot analysis of your silver, platinum, and PGM metals and impurities, making it an easy way to boost customer confidence and ensure dealer reliability.

Given the current high value of gold, quantifying its fineness and purity is more critical than ever. Whether you buy gold, sell or produce jewelry, fabricate metal, or recycle scrap metal, you need a fast, highly accurate method to determine karat (gold content) for quality control and pricing.

The Htek EDX-6000 XRF analyzer is an easy-to‑use, cost-effective method to obtain alloy chemistry and karat classification with one nondestructive and nonintrusive test. Additionally, an exclusive Htek EDX-6000 software feature helps identify gold-plated objects and sends an alert to the screen.

Features and Benefits
