To understand the value of XRF gold analyzers in the jewelry industry, it is first necessary to clarify their core working principle—X-ray Fluorescence (XRF) technology. Unlike traditional destructive testing methods, XRF technology achieves non-destructive, rapid, and accurate element analysis through physical processes, which is perfectly aligned with the high-value and precision requirements of the jewelry industry.

1.1, Basics of X-ray Fluorescence (XRF) Technology

The working principle of SuperbMelt XRF Gold Analyzer (XR3800) is based on the X-ray fluorescence effect: when the low-power X-ray tube (the excited source of the equipment) emits X-rays to irradiate the precious metal sample, the atoms in the sample will absorb the energy of the X-rays, causing the inner-shell electrons to transition to an excited state. When the excited electrons return to the ground state, they will release characteristic X-rays with specific energy. The equipment’s detector captures these characteristic X-rays, and through the built-in intelligent software (based on Microsoft Windows system), it analyzes the energy and intensity of the X-rays to determine the types and content of elements in the sample.

Key advantage: The low-power X-ray tube of the SuperbMelt XR3800 not only ensures sufficient excitation energy for element detection but also minimizes the risk of damage to precious metals during testing—completely avoiding the sample damage problem that plagues traditional testing methods.

1.2, Why Non-Destructive Testing Is Essential for Jewelry

For the jewelry industry, non-destructive testing is not a “value-added option” but a “basic requirement.” The core reasons are as follows:

• Protecting High-Value Products: Most jewelry products (such as inlaid rings, delicate necklaces, and limited-edition gold coins) are high-value finished products. Destructive testing (such as cutting samples for fire assay) will directly damage the product’s integrity, reducing its value or even making it unsellable. SuperbMelt XRF Gold Analyzer can complete testing without damaging the sample’s appearance or structure, maximizing the protection of product value.
• Meeting Transaction Transparency Needs: In jewelry retail, recycling, and pawn transactions, customers often require on-site, visual testing. Non-destructive testing allows the tester to operate in front of the customer, displaying the analysis results in real time. This enhances transaction transparency, eliminates customer doubts about “sample replacement” or “damage to the product,” and builds trust between the two parties.
• Adapting to Diversified Sample Forms: Jewelry products have diverse forms—solid finished products (rings, chains), semi-finished materials (gold bars, silver sheets), and even raw materials (metal powders, mineral ores). Non-destructive testing can adapt to various sample forms without special sample processing, improving testing efficiency.

1.3, Differences in Testing Solid, Liquid, and Powder Samples

SuperbMelt XRF Gold Analyzer (XR3800) has strong compatibility and can handle solid, liquid, and powder samples common in the jewelry and precious metal industry.

• Solid Samples: The most common sample form in the jewelry industry, including finished jewelry (rings, chains, bracelets), gold bars, silver coins, and scrap gold. Testing only requires placing the sample on the measurement window of the equipment and clicking “measurement start”—the intelligent software will automatically complete the analysis. For irregularly shaped solid samples (such as twisted chains), the equipment’s high-sensitivity detector can still accurately capture characteristic X-rays, ensuring analysis accuracy.
• Liquid Samples: Common in jewelry manufacturing auxiliary materials (such as electroplating solutions, metal refining solutions). When testing liquid samples, a special sample container (provided with the equipment) is required to hold the liquid and place it on the measurement window. The equipment can quickly analyze the element content in the liquid, helping manufacturers control the quality of the production process (such as ensuring the concentration of gold ions in the electroplating solution).
• Powder Samples: Including metal powder raw materials, mineral ores (gold ore, silver ore), and scrap metal powder.
