• Centralized Gold Evaluation Units 

Its simplicity, speed, and repeatability make it ideal for both frontline officers and centralized risk teams. 

The Scientific Testing Method: How XRF Works  

​The DX800N utilizes Energy-Dispersive X-ray Fluorescence (EDXRF), a highly sophisticated, non-contact analytical technique. Here is the step-by-step science behind how it evaluates your gold:

​X-Ray Excitation: The analyzer emits a controlled, low-energy primary X-ray beam directly onto the surface of the sample.

​Atomic Displacement: This X-ray energy knocks loose electrons out of the inner shells of the atoms within the metal sample.

​Fluorescence Emission: To regain stability, outer-shell electrons drop down to fill these vacancies. As they do, they release a specific burst of energy in the form of secondary (fluorescent) X-rays.

​Elemental Fingerprinting: Every element on the periodic table (Gold, Silver, Copper, Zinc, Nickel, etc.) releases a unique energy signature during this process.

​Spectrum Analysis: The DX800N’s high-sensitivity detector captures these signals. The integrated software instantly processes the data, translating the energy peaks into an exact elemental percentage breakdown (e.g., 99.98% Au) displayed on your monitor.

Key Advantages for Banks & Pawn Brokers    

• Complete Non-Destructive Testing (NDT): Unlike traditional fire assaying or acid scratch tests, the DX800N leaves the sample completely unmarred, unaltered, and intact.

• ​Rapid, Multi-Element Detection: Get comprehensive results in as little as 10 to 60 seconds. It simultaneously detects not just gold, but silver, copper, platinum, palladium, and prohibited deleterious elements.

• ​Uncompromising Accuracy: Equipped with advanced hardware algorithms, it easily distinguishes between genuine gold karats, gold plating, and deceptive counterfeit alloys.

• ​User-Friendly Software Interface: Operates on a seamless Windows-based platform, generating automated, easy-to-read certificates and evaluation reports at the click of a button.

• ​Safe and Eco-Friendly: Replaces hazardous, toxic chemical acids and high-heat melt testing with an enclosed, radiation-shielded chamber, ensuring 100% operator safety.
