Energy Dispersive X-ray Fluorescence Spectrometer

EDX-8000 SDD XRF Gold Tester

Overview

The assay lab that gives you completely non-destructive precise results in second

The energy dispersive X-ray fluorescence spectrometer (EDXRF) technique is one of the most versatile and popular analytical methods for the elemental analysis of Precious metals and karat identification. All the noble metals can be analyzed in a short period of time with high accuracy, precision and reliability. The virtue of its simplicity, non-destructive, speed, affordability and reliability are clearly advantageous over traditional wet chemistry (fire assay for example) and other spectroscopic methods. Modern technological developments have also helped to include EDXRF into standard test methods for Jewelry application. With the latest Silicon Drift Detector technology, EDX-8000 ensures the highest precision with the shortest test time. Higher Count rates, better spectrum resolution with small 1mm spot size of collimator are all critical parameters for the gold analysis application, which are all achieved by the EDX-8000 XRF spectrometer. This application note proves that EDX8000 is mature enough to establish clear qualitative and quantitative characterization of the gold value as well as Karat grade.

Features and Benefits

>Large sample chamber with the best performance Silicon Drift Detector

>Outstanding sensitivity leads to up to a factor 3 improved precision – the basis for high accuracy when analyzing minor to major element concentrations. 

>World’s fastest XRF analyze–highest accuracy within the shortest measurement time, excellent precision

>High-count throughput detection system result in significantly (typically a factor 3) lower limits of detection for a wide range of elements.

>Easier, faster, more accurate than nitric acid test methods.

>Faster, more comprehensive analysis than fire assay, with comparable accuracy.

>Measure the content of all gold and precious metals without manually changing the calibration.

>Precisely determine the presence and concentration of other trace alloying elements and dangerous heavy elements, which could impact valuation and future refining needs.
