Precious metals are used not only for jewelry? Certain electronics, lab equipment, even the banking industry, and medicine can’t make it without high-quality precious metals. To make sure the properties of the material are appropriate for usage in a particular business, it has to be analyzed. Precious metal XRF analyzer is made exactly for this purpose.
It’s crucial to know what additions there are in the alloy or what additional layers the “clean” metal has as they affect the strength, resistance to corrosion and other damage, and ductility. This is where XRF (X-ray fluorescent) technology helps.

XRF Technology for Precious Metals
Nowadays, XRF technology is the best solution to determine the full composition of any precious metal. The advantages are plenty and resolving most of the issues of the old analysis methods:
- No material loss and metal destruction/breakage
- The analyzed item remains of the same weight and form
- High accuracy and speed; you can see the full result report in several seconds
- A wide range of sizes and shapes of objects that can be analyzed
- All-component XRF precious metals testing that doesn’t prolong the procedure
- Recognition of harmful elements like Ir, Cd, Ru, Pb, as well as coatings such as gliding
- No consumables needed
- The objects don’t have to be prepared to undergo the procedure
How does a precious metal analyzer work?
XRF precious metal analyzer utilizes the effect of X-ray fluorescence, which is the result of the inelastic scatter of X-rays on the sample. The characteristic spectrum produced by different samples on such interaction can be used to evaluate their composition, as each element has its own set of characteristic X-ray lines. XRF metal analyzers provide accurate results, are portable and relatively easy to operate which makes them a popular tool for material analysis in many different spheres. Precious metal analyzers are one of the most common applications of X-ray fluorescence, as all precious metals, including palladium, rhodium, and other elements of the platinum group, as well as most elements that can be encountered in precious alloys, such as copper, lead, or cadmium lie within XRF methods detection range.
XRF analysis in comparison with other popular methods of testing precious metals
Alongside XRF, typical methods employed for precious metals analysis are the acid test, fire assay, and conductivity test. The acid test is a technique based on the measurement of the solubility of a sample in acids of different strengths; however, this method will only provide the closest jewelry grade that matches the sample, and cannot be considered a quantitative method. Conductivity measurement, while simple and cheap, can be unreliable and has poor accuracy due to temperature dependence of sample conductivity and the fact that some alloys and mixed metals may have similar conductivity levels. Unlike these two methods, XRF metal analyzers provide a sample’s quantitative elemental composition, allowing easy and accurate analysis.
Fire assay is probably among the most accurate measurement methods however, this method takes a few hours to perform analysis and is destructive. This makes XRF analyzer for jewelry a more appealing option, due to its nondestructive nature and comparable analysis accuracy.
Overall, XRF precious metal testing machine combines the accuracy of fire assay with the simplicity and non-destructive nature of X-ray fluorescence method, which makes it a perfect tool for precious metals analysis.
