With the high price and volatility of gold today, more efficient gold-testing methods are being used to establish the value of items like jewellery or coins being purchased, sold, or recycled.
Testing gold and precious metals demands accurate and reliable results to eliminate variability and subjectivity, and ensure fair transactions.
That’s why businesses turn to our portable X-ray fluorescence (PXRF) analysers for fast, accurate, and non-destructive analysis of precious metals entering their shops.
In as little as 3-10 seconds, our XRF analysers provide exact karat weight and percentages of all elements within an item they test, enabling them to detect non-standard and counterfeit gold with the accuracy of a fire assay.
The electronic testing approach also appeals to people who don’t want to deal with acids in the testing process.
The most advanced portable electronic gold tester is an XRF.
These battery-operated testers contain an X-ray tube and shoot a small X-ray beam at the piece being tested.
The beam interacts with the elements in the piece and the machine reads the results.
The PAS Range Of Analysers For Gold Buyers
XRF precious metal analyzer supply concentrations for 21 elements and karat values in seconds.
Our Thermo Fisher Scientific Niton DXL and Niton XL2 precious metal and gold purity analysers are equipped with proprietary, patented AuDIT gold-plating detection technology.
Several independent, complementary methods in the AuDIT (Au/gold Detection & Identification Technology) software work in tandem to alert you to the probability that an item is plated, regardless of the gold concentration of the plated surface layer.
AuDIT technology works for vermeil (gold-plated silver), as well as gold-plated copper, steel, tungsten and any other non-gold substrate.
Precious metals and gold testing machines simultaneously measure the content of all gold and precious metals without manually changing your calibration based on the metal you’re analysing
Precisely determine the presence and concentration of more than 22 precious metal and trace alloying elements, including but not limited to gold (Au), Silver (Ag), Platinum (Pt), Palladium (Pd), Nickel (Ni), Tungsten (W), and Lead (Pb).
