Small spot energy dispersive X-ray fluorescence (ED-XRF) spectrometer optimized for precious metal testing


  • Top-tier precious metal analysis with 30+ calibrated elements.

  • Unmatched accuracy for traces and majors.

  • Opt for swift exceptional results or efficient standard results with up to 3x faster measurements.


Accuracy of elemental analysis is often critical — especially in assessing precious metals. For other applications speed is even more important: High-volume hallmarking centers demand both fast and accurate analysis. In addition, all users prefer analyzers that are robust, convenient, and easy to operate, with helpful software and easy transfer of results into a lab network. In dealing with precious metals, of course, users also prize nondestructive sampling.

For years, SPECTRO MIDEX has turned in ultra-reliable top-rated XRF performance in all these areas. It’s the industry standard in many assay laboratories worldwide. Now a fifth generation of SPECTRO MIDEX analyzers — with up to triple the sensitivity even of previous models — approaches fire assay technology in precision, while greatly surpassing it in speed and ease. And it’s fully optimized for precious metals applications.

The compact new SPECTRO MIDEX incorporates the latest developments in ED-XRF detector technology, using high count rate and high resolution. These smart new innovations help make it one of the most advanced midrange laboratory XRF benchtop analyzers available for precious metals testing. So users can choose significantly increased precision — even for minor and trace element content — or substantially faster testing for higher sample throughput.



 Precious metals testing with ED-XRF spectrometry (XRF-101-AB)

Precious metals demand careful analysis.

This paper examines the use of the SPECTRO MIDEX with regards to precious metals testing. With considerable improvement on already high levels of precision and speed, it provided excellent analytical results.
