X-ray Fluorescence for Gold-Buying Industry

Gold and Jewelry Quality Testing

Since the economic crisis the gold price is steadily on the rise. These historically high gold prices boost the importance of so-called “cash for gold” businesses. Because the buyer usually has only a few minutes to estimate the value of gold items presented for sale, methods like touchstone analysis are often used: Although this test severely scratches the piece it is still not 100% reliable. The industry demands a precise, quick and foolproof method for testing gold content that is, above all, non-destructive.

Besides the weight, the gold content of an object determines its value. The commonly-used analysis methods pose different disadvantages for retail buyers of personal gold items: Fire assaying is time consuming and relies on chemical processes, and despite the fact that touchstone analysis also requires acids for testing, the results are still not always reliable. Because both methods damage the item in varying degrees, neither really meets the needs of the industry.

However, X-ray fluorescence analysis (XRF) offers a non-destructive method for quick material analysis and coating thickness measurement on jewelery, watches and other precious metal products; Fischer’s XRF instruments are simple to use, even for non-technicians.

The GOLDSCOPE SD® 520 enables precise and reliable determination of gold and platinum content even under challenging circumstances. Fast and easy-to-use, the GOLDSCOPE SD® 520 features excellent long-term stability and rarely ever requires calibration. Operation is as simple as opening the hood, placing the item on the inspection window, closing the hood and starting the inspection with the press of a button. In less than a minute the exact content of gold and various other elements is presented on the screen.

Functionality and the minimization of running costs took high priority during development of the GOLDSCOPE SD® 520. Designed without moving parts – thus eliminating wear and tear – the GOLDSCOPE SD® 520 is truly a precision instrument meant for real-life, daily use.


  • Fast: results in less than a minute
