The Thermo Scientific XRF Precious Metal Analyzer

Given the volatility and high prices of gold, precious metals, and gems, you simply can't afford the delays or potential inaccuracies of traditional testing methods used to assess the value of items being bought, sold, or recycled.


With Thermo Scientific™ portable X-ray fluorescence (XRF) analyzers, now featuring Thermo Scientific AuDIT™ gold-plating detection technology, you can determine the precious metal content in jewelry, coins, and other valuable items in just a few seconds, achieving fire assay-comparable accuracy.


It takes just one push of a button or a simple trigger pull, and you'll receive an accurate purity analysis almost instantly, enabling on-the-spot sorting and valuation of gold and all precious metals, as well as quantification of other desirable and undesirable elements.

What Our XRF Technology Can Do

Given the worth of gold and other precious metals, it is essential that no material is wasted during the testing process. Our portable XRF technology offers analyses that are:



  • Rapid
  • Dependable
  • User-friendly (requiring little to no sample preparation)
  • Nondestructive (free from harsh acids or chemicals).
