Spectral analysis of precious metals

Learn more about the precious metals analysis services using spectrometry, offered by RAFINOR!

After the material containing precious metals is processed in our refinery, samples from each batch are sent to the precious metals testing laboratory. These samples are tested to determine the type and content of precious metals.

We can detect gold, silver, platinum, palladium, and rhodium, as well as other elements, using tests that include X-ray spectrometry analysis. Depending on the metal type, we can provide on-the-spot results within seconds. The exceptional speed and reliability lead to optimal productivity, reduced costs, and a significant competitive advantage.

What is the spectrometry method?

The spectrometry method is a technique used to analyze and measure the properties of materials, such as precious metals, based on their reaction to light or other types of radiation. Essentially, this method helps identify and quantify the chemical elements in a sample, providing detailed information about its composition.

How does the spectrometry method work?

The spectrometry method is extremely useful in the precious metals industry because it allows for the rapid identification of gold, silver, platinum, and other valuable metals, even in complex mixtures. It helps determine the quality and purity of materials, making it an essential tool for metal testing and refining processes. RAFINOR uses spectrometric technology to obtain fast results, helping to optimize refining processes and ensuring the quality of the analyzed precious metals.

Advantages of the spectrometry method

• High precision: Accurately identifies the composition of precious metals and alloys, with a margin of error of approximately ±0.1–0.2 carats or ±0.5% of the composition.
• Speed: The analysis takes between 5 and 60 seconds, facilitating evaluation and trading processes.
• Non-invasive method: Does not damage or alter the samples.
• Reliable and cost-effective: Unlike traditional chemical tests, it requires no consumables.
• Detects unwanted elements: Identifies impurities and hazardous metals.

These advantages make the spectrometry method extremely useful for precious metal analysis—whether for assessing the quality of gold or silver, or for certifying their purity in production or industrial refining processes. In addition to spectrometry, RAFINOR also performs chemical analysis of precious metals, providing a detailed evaluation of their composition.

The spectral analysis procedure for precious metals at RAFINOR

At RAFINOR, spectral analysis of precious metals is a carefully regulated process, ensuring accurate and reliable results. The procedure involves the following steps:

1. Sample preparation: Materials containing precious metals such as gold, silver, or platinum are prepared according to specific technical requirements to ensure effective analysis. The process may include cleaning the sample and obtaining a representative portion.
2. Purity assessment: Based on the spectrum obtained, the purity of each precious metal present in the material is determined, along with the exact composition of the alloy or material. This information is essential for evaluating the material’s purity. At RAFINOR, we carry out precise analyses of precious metals and are also interested in purchasing precious metals from authorized companies and organizations. we buy precious metals from approved companies and organizations.
3. Testing report: After completing the analysis, a detailed report is generated, offering accurate information about the type and amount of precious metals, as well as any other chemical elements present. This report can be used to certify the purity of the metals or to assess the material’s quality before the refining process.

The RAFINOR team offers high-quality services for precious metals analysis, using precise and efficient methods. Spectral analysis allows for the fast and accurate determination of metal composition, and we guarantee reliable results. Whether you're evaluating the quality of gold, silver, platinum, or other precious metals, we help you determine the purity and value of your materials.
